Just bought the p365X a week ago and took the Romeo Zero off to put a 507K x2 on it. I love it!

I feel your comparison was very fair and honest. I have a Holosun on my rifle and absolutely love it. I also have the Romeo Zero on my Sig and really like it too. Using both sights, I must agree 100% with your review

Very matter of fact, unbiased and important features focused review. Thank you

Another great review that will take my money.

Just got my 407K X2 based on your review and I love it!! Thanks for the videos keep them coming.

Great review. I just picked up the 507k in green, before watching your video, and for almost all the reasons you mentioned. I spent the extra bit to have the flexibility of going dot to outer ring to a combo of the two. I did a lot of looking and really like the features you mentioned. You are spot on, the weight is negligible, the housing on Holosun is really nice, and for those of us getting older eyes, the dot really allows for easier pickup and sight to target alignment.

High five to Indiana. I don't live there, but have been many time. People were always friendly and pleasant to be around. All The Best

Thank you so much for this review. I know I'm swapping my EDC to the sig p365 xl, I just couldn't decide if i wanted the already installed romeo or the holosun. This just made up my mind! I'll be purchasing the pistol tomm and hopefully the 407k next week.

Thank you so much for this outstanding review as was considering both for my 365 and FN 509...just ordered 2 Holosuns....subbed 👍

Best comparison video out there. Thanks for helping me choose. Before watching this I was really unsure which to buy. But now it’s no question. Thanks brother. God bless.

Appreciate the comparison. My HS507k is waiting its turn to be put on my 365 right now. (not XL). So excited. The thing just reeks of quality. Very nice. (I have a bunch of HS on ARs too. Love the circle dot.)

Awesome review. Thank you! Going to pick one up soon with green dot.

I just ordered the Sig for my Glock 48 because the Holosun 507K I ordered three weeks ago apparently won't get to me for months. The Sig was in stock so I'll use it until my Holosun gets to me. :) Great review.

Thank you for your honesty you have a new subscriber I almost pulled the trigger and purchased a 365 compact with the Romeo on it last night now I am going to reconsider

Great video. Answered my questions!

Poe , I'm with you on choice the Holosun would be my first choice no doubt and also looks better on your p365xl than the sig, very informative video.

Good video definitely helped make my decision. 407 but might spend the extra for the 507.

Awesome review of the Holosun 407 and the Sig Romeo. Great video review and spot on concerning both MRD's. Having watched several video reviews of the Holosun MRD sights, I'm impressed with the Holosun Red dot sights. For the money you can't find a better MRD sight!! I really like the Holosun's circle dot combination as it helps us now old guys eyes. It allows you faster shots on target and follow up shots!! I'm waiting on a Holosun 507C VR2 now to be in stock at Midway. For the fans of Glock pistols, Strike Industries has an affordable slide already milled for an RMR style MRD for $200 in black. You will also need to order a firing pin channel liner or a complete upper parts kit and suppressor height night sights inorder to co-witness your sights and MRD in the lower 1/3. This option allows you to keep your original Glock slide. I'm sold on Holosun MRD's it's also affordable than the RMR. The money saved by buying the Holosun can go for money training ammo!!! Have an Awesome day and Stay Safe and watch your six. Reb out.

Was having a very hard time deciding between these exact two sights and this helped me more than you know! Thank you so much! Great video!

I love my 407k. Built in rear sight. Auto off. Green 6 moa dot. And you don’t have to remove the dot for battery replacement. No contest.

Thanks for being fearless great video

This video convinced me which one I will be putting on my P365X, thank you

I own both. They are both very good red dots. I have no problem with either one.

i own several holosuns and rmr's. i actually prefer the holosuns for faster acquisition. they have operated flawlessly for a few years now.

Thanks for the useful information! After watching your video and several others (i.e. Sage Dynamics), I just ordered a 407k X2 in green for my P365XL. Best price I could find was $240 (delivered). For me, the 6 MOA is perfect for self defensive use, and the green seems to work better for me because of my astigmatism. I've got an RM06 (6.5 MOA) on my shotgun that has held up to several hundred rounds (including a few boxes of 3" magnums), but for the smaller P365XL, I think the 407k was the best choice. Now, I have to mount it and spend a few weeks and many rounds for training...

Great review! I’m going with the Holosun!

Good review and comparison, thanks!

This is a very well done video. I have two pistol RMRs and two rifle mounted Holosuns. I am now convinced to buy a 407k. A friendly suggestion for production value, invest in a wireless body microphone to improve audio quality and eliminate the echo effect.

Say what you want about holosun they are great products. I own 2- 510c, 507c, 407c, and a 403. And soon the 407k for sure. Never had any issues with them. Highly recommend them. Great video.

Just the video I've been looking for. Thank you!

Well I wish i would have seen this about 7 hrs ago! Just bought the Romeo Zero! Oh well I'm glad you at least liked it. My p365 is off to the mill in the morning!

You have convinced me on buying the Holosun.

great comparison. helped me decide on the holosun. thanks.

Wow, super thorough. Thanks!

I just bought a sig p365XL With the Romeo zero Haven’t pick it up yet but when I do I will get the holosuns 507k to go with it. Your review made my mind up. Thanks

Another great video, thanks.

Thanks much for the info . Great video. It answered my questions completely and made the decision I was going to make easier.

Thank you for the in-depth review! Very helpful

Great video, although I'm a little biased as I've had a Holosun 507k on backorder for weeks. Thanks for affirming I made a great choice, now I just hope Optics Planet eventually comes through....

Just mounted the Romeo on my (California) P365, and I appreciate the simplicity of this sight. Simple, light, and fits like a glove. I adjusted the dot merely by looking down the sight path while at home just so I can see the dot move. Now that I have the dot's brightness adjusted and aligned to my sights I will take it to the range for the REAL test. I hope I am happy with it's performance, otherwise, I will just get something different. The two main draws for me regarding this sight was the name (Sig on a Sig!)... and the PRICE ($98.95)! Only time will tell...! 😊

Great video! Thanks for sharing and I appreciate your recommendation! 🍻

I have been researching both optics and have been leaning toward the Holosun 407K. This review helped me make the final decision. Holosun it is - thank you!!

I use a pencil with an eraser to turn on and off my Romeo Zero. I also have optional metal shroud. That being said your review is spot on

I have a new Romeo Zero that I bought just a few months ago no more than 3 and the battery was dead already. I opened it up and it has no plastic cover over the battery and the battery was laying on the slide when I removed the Red Dot. I will be getting a Holosun as I was already a believer in their products.

Great review Poe!

Great video I carry the Romeo zero off duty and battery changes are frustrating throws off the zero you sold me.

Great video Poe, I've been researching weather to go with a RMRcc or the H407k and I've about made the decision to go with the Holosun. I know the rugged dependability and indestructible construction of the RMR is hard to beat, but it's hard to pull the trigger and spend more than double on the Trijicon when you can use the money to spend on the milling that needs to be done on most handguns including my 43x. Keep up the great work I look forward to the next video brother.

Concur. Just went from a Romeo Zero on a 365XL to a 507K-X2. The Zero worked fine until the battery died about 4 months in. Bought the 507K . Couldn't find anyone with a 407K in stock. Bought it mostly because of the side battery port. Literally everything about 507K/407K is superior to the Zero. I have a Sig Romeo 4S on an AR pistol and the reticle set up has an almost identical circle dot setup. Pretty sure Holosun is the OEM for Sig RDS optics. I love the 365XL and the 507K actually does it justice. The 'Zero always felt kind of cheap. My guess is both RDS are manufactured in China. FWIW I put a Leopold DPP on my FN 509 T... so I buy American when I can. Great vid. Thanks.

I'm still evaluating and remain an open mind regarding optics versus good iron sights. I presently have the Romeo 1 Pro affixed on my P229 Legion. A pistol I love to shoot but is not my edc. I truly enjoy the experience. My edc is the P320 X Compact with the provided Sig X-Ray night sights. I'm still not convinced red dots are an answer for me. For me a lot can be said for the simplicity and reliability of irons. Especially in a defensive situation. I'm still, over a year later, working through it. Appreciate your time, efforts to inform and give opinion. Carry on!!!👍👍

I started with the Romeo o battery lasted 3 months when i took it off i put holosun 407k x2 7 months later love it. Didn't like adjustments on the Romeo every time i smeared the lens with my finger. Holosun is just better.

Doin good work Poe!!!

507k W/TITANIUM CASE Green Laser is what I'm waiting for. . Have a 507TGR mounted on my ZEV// Custom Blaster built on a new Glock Gen3 frame.I want one for a P365 XL, BEST all-round carry weapon and I am a Glock fan. Have 5 of em.

I don’t have any holosun Products but I do have a P365XL with the Romeo zero already installed. I am amazed how good that red dot is. Highly recommend Romeo zero, if you’re going conceal carry with the red dot. But I’m sure that packaging is to save the customers money.

Just bought a p367XL and it came with the Romeo 0 already on it

Great info and thanks for showing these side by side! You are a great Patriot!

Nice job. I'm a 68 yr old first time gun buyer with 2 days to go on my 8 day BCI waiting period.Unless our government comes up with some bogus reason to screw with me I will be picking up my Kimber r7 Mako and needless to say I'm pretty excited. If all goes well I think I'll be getting a Holosun 407k.You convinced me! I'll subb.

I hit the like button and subscribed once you said KZfaq will ding for letting a dot sit on a slide. I don’t think people complain of the logo. But how bold it looks on this dot.

Great video! Thanks 🙏

Good unbiased video! My HS507K should be delivered tomorrow.. finally! I waited over 4 months since I preordered it. Also, I subscribed to your channel. I really like the fact that you also took the time to look through the comments and answer many viewer questions. 99 percent of the comments were mature and informative.

I really liked the Romeo Zero but the lens got so scratched up just from shooting I sent it back for a replacement. The replacement was more of the same so I literally just sent it back today. I’m just gonna buy either the Holosun 507k or the 407k.

Thank you for your video very constructive feedback

Good job, never the Romeo 0 (poor build and material), but the Romeo 1 and 1 Pro are much better. I really like Sig products; however, the 407K is everything I was looking for in a red dot at a fantastic price, material and functionality. Great review comparison PO; keep it up. I am becoming a fan.

Great video I just got a hellcat pro and it’s the OSP which I think is the RMSc cut and the Holosun needs an adaptor plate to mount to my slide or grind off the bottom 2 posts. It fits the Hex Wasp, the Shield RMSc, one of the swamp fox and the tirjicon cc model!! I wanna do a 507k

Great info. Thanks!

Well damn...the video you did on the Romeo Zero was having me itching for one of those, but now..I may look for the HS507K, just for that little extra above & beyond the HS407K!!! :)

Just put the 507k on my 365xl. I agree on choosing it over Trijicon. Holosun has way better features for far less money. When Trijicon was a one horse show they could demand any price they wanted but they no longer are, nor do they lead the engineering behind the red dots.

Awesome review I own both and I like both but the holosun 507k is just better I already have scratches on my romeo zero and it's less than a month old. I was extremely easy on the romeo zero but still scratches way to easy

I have both on two P365XLs.. the Holosun is definitely more rugged, and prefer the 6 MOA dot, but if you compare the sight picture side by side...the Romeo Zero is much better with no distortion. Don't believe me - compare them both indoor in medium light conditions. I conclude the lower image quality of the 407 is attributed to the angle of the glass. Anyhoo...great review of these two micro sights. 👍

New sig sights come with shroud. I have one on the way. Sig is sending me replacement. Apparently there was a batch that still passed QC and somehow the develop issues with elevation adjustment

Had 2 rome zero's and both had zero shifts and would adjust to the right regardless of which way you turned the screw. Sig told me to send them both in to be re centered and to not adjust the zero. I would get the holosun any day.

I have 2xl's an 2 years ago I paid 75 dollars to a guy trading up to holosun 407. Cheap enough to learn on but you are right plastic lense and battery on bottom. We like the 407 much better. I still have the romeo on one but when battery dies will trade up. Subbed

I’ve got the Romeo Zero on my P365XL, here’s my take. I’ve been carrying a P320cRX so the Romeo Zero feels natural to me, I prefer the arched top of the Zero over the square top of the Holosun, I think the arched top provides a better sight picture. I also think the image on the Zero is slightly better (slightly clearer lens and slightly better dot clarity). I like the way the Zero is purpose built to match the P365 series so it looks great on the gun. The Holosun is built like a tank and would survive hard use or a drop, it has double the battery life and doesn’t need to be removed to change batteries, has more adjustments and buttons to move the brightness up or down (Zero you have to cycle through). There is just not much not to like about the Holosun. So I’m keeping my Romeo Zero but if it gives me any trouble (like poor battery life), Holosun 407 will be the replacement, (I’m not a fan of the 507’s 32moa circle reticle).

Thank you

Great info Thank you.

Good review

I may have to consider getting a red dot Always been irons but my eyes are getting tired and even with glasses sometimes it adds a little time Thank you for the great review/comparison from your neighbor in Michigan

Nice job

I’m currently trying to send my Romeo zero back to Sig because it didn’t allow me to adjust the elevation at all. Plus the lack of clicks when attempting to adjust was disappointing. Overall i was underwhelmed and will probably sell my replacement unit...... if I ever get it

Just ordered the holosun 407k X2 off Amazon was 220.00 I think I got the sig p365 x macro a couple weeks ago finding it harder and harder the find the sights at 54 years old now hope this red dot works out..I have the same flags 👍🏻👍🏻

Amen, the Holosun is the ticket

Thanks for actually being willing to state a negative opinion. major channels get stuff for free and are a lot less likely to be critical, even when warranted.

Yea i should have seen the review on both earlier, I bought the Romeo and did want to install it but trying to take the screw off was a pain , it is stripped now have no chance of saving it now unless I get a gunsmith but I figure I sell the sight instead or pistol

Found 407k in san antonio visiting friend for 289. Bought it because I have been looking for one. Everywhere is sold out. Almost bought all 4 because I watched 2 on ebay go for around 500.

Mounting the same for both? Or do you need to use adapters for the holosun? Thanks much Fantastic review

I have both and the romeo 0 has been a nightmare. I have noticed that if you zero on a XL or longer slide it has no issues. However , if u zero on a regular p365 or Hellcat it won t zero. I love the 507k and rmsc though. I only wish the 507k had the auto brightness like the rmsc or rmr

Holosun no questions about it!!!

Thanks for a very well done video ! by the way, I need your recommendation/suggestion ..what would you recommend for self defense ..the 407k or the 507K ?

Thank you 👍

Poe, your video review was outstanding. I have the 365 XL as my carry gun of choice. I have had it for several months now and love it My eyes aren't what they used to be due to advancing years (>70.) I have a question for someone to answer. 1. 6MOA vs 3MOA which one to choose? It is pretty much a moot point because neither one is available right now everywhere. Again, love your content.

Love my holosun had 3 for years thousands of rounds not had any failures

Thanks , teeter totter convinced

Went with the Holosun 407k for my 365xl EDC. You can get the Holosun 407 around $224 but I saw that Sig is coming out with a Romeo Zero Elite which looks like the original Zero that got all the upgrades from the complaints. Interested to see how that one compares to the 407/507 Holosun.

I own both, I'm a Sig guy, but the Holosun 407K is superior in almost every way. Word to those about to buy the Romeo Zero...you must adjust the WINDAGE FIRST, THEN THE ELEVATION! You run the risk of stripping the windage set screw if you tighten the Elevation screw first. Had to send mine back to Sig. Took weeks to get it back.

I want to get the 507c for my p320 but, I have to optic cut my slide first.

I'm buying the Holosun.

Bought the P365XL w/ romeo zero package 3 months ago. Romeo Zero did not cowitness with back up sites. Wrote to Sig customer service and was sent a new replacement Romeo zero. 2nd new Romeo also broken, would not turn off , would not adjust brightness. Wrote back to Sig, sent New Romeo back and requested Original Iron back sight assembly as i will NEVER trust the romeo zero again while on my p365 edc. No back sight assembly available but put on Sig wait list. That said. 2 weeks ago, Botach had a huge shipment of about 100 Holosun 507k for sale on ebay! Bought 2 507k for $289 each! Score, thank god for Botach. Now i'll have a red dot back on my P365XL. Botach sold out in less than 24 hours. NO, i do not recommend Romeo Zero. Also, was sent a sheet metal protective cover with Replacement Romeo Zero. Cover was blued so expect rust issues under mount. Sig answer to protect plastic body incase you drop weapon. But when installed, increased overall weight, height, width. Not worth it, go for Holosun, if you find one.

Will the Halosun solar HE407c grx2 fit on the Sig p365x? I was looking at the description and it said its for "full size" handguns.

I agree BUT @$139 on the RomeoO -I’m going with Sig.

I bought the holosun for my GX 4 Toro today. I may put it on the 365xl instead and move the Romeo to the Toro.

Thanks to my 407k and my 365xl with the shields threaded barrel I can place 25 shots slow fire in the 10 ring at 30 feet
