I had to check when this aired when he said " handgun ammo in the scheme of things doesn't cost that much" yeah the good ole days lol

It absolutely blows my mind the wealth of knowledge you have and are willing to share. I have never once skipped even a second of your videos. They are literally a goldmine

This channel is so freaking underrated. Easily should be a 1mil+ subscribed channel.

10:23 Yeah those were the days. August 2020 here.

Watching this later. I’m going to start using red dots soon. Your videos on red dots are all saved for later. Thanks so much for these.

This came out at the perfect time. I just bought my first RMR (RM06) and as soon as the sights get here (friday) it's going on the gun. Another chunk of information right when I needed it 🤙🏻

Aaron is an absolute gold mine of information. Anytime I’m going to make a purchase, I check and see if he has a review on whatever it is I’m buying. Love your content Aaron! Keep it up

Thank you! Your technique, conservative adjustments steps, and detailed narrative are my now gold standard. Investing so much time for sharing knowledge vs. learning is greatly appreciated! Your videos in general are outstanding! Thanks again.

Another great explanation and I got the first video. Since I have and MRO on my AR15 that I full co witness, I just zeroed the RMR directly not relying on slaving. Didn’t see the need to. Your videos helped me adjust to it very quickly and I appreciate it. “Raise the back plate to your nose and you will pick up the red dot”. The best tip!! Thanks Aaron.

Thank you for this video. Definitely cleared up the bit of confusion that was left about zeroing a red dot, at least for me. Looks like I've got some range time when I get home!

Great video that goes step by step on the zeroing of a handgun optic. Thank you foe the knowledge.

Wow! This is the best video I have seen on zeroing the red dot. Thanks!

thanks for the clarification. I actually commented on your last video when you said you should never slave your red dot to your iron sights and referenced an even earlier video when you said you should...now it makes sense. I really enjoy your videos. Your passion educating people really comes through. No ego or macho bullshit, I wold love to attend one of your training classes.

Aaron in 2020: "Handgun ammunition in the grand scheme of things isn't all that expensive." Me in 2021: "It just cost me $25 to zero my red dot."

I appreciate that your videos jump right in and get to the point.

Very informative update video. Thanks for taking the time to make this. I’m going to go back through my zero on my CZ P10C with an RMR while using this video to make sure it’s right. This year I’m going to make sure I take a handgun training course. I would love to take a carbine course also but I don’t think the funds will allow both. That will give me something to look forward to for next year.

Bro Aaron, you are becoming the YT king of weapon and ammunition eduction. Love your content, deliverey, and knowledge of all your work.

Thanks for this video, I am getting ready to do a glock mos build with a trijicon rmr hrs. I will definitely be watching this again when I get finished with the build.

Thank you for the info. I’m new to using RMR and this is very helpful.

Thank you for you insight into this! I started the slave process but didnt think about swapping out to the actual carry ammo, the thought never came to mind! This is why i love your videos, you make me think and point out when i dont! Cant wait to see you review the up coming Aimpoint ACRO sight to see how it compares to the tried and true RMR's.

Dude, you’re so clear. An outstanding teacher. Thank you.

Excellent method. Im old school and feel very at home w good iron sights. However a properly zeroed red dot is pretty damn incredible. Thank you for sharing. Used this w my optic cut. Thanks

Aaron you absolutely rock! Thanks for posting this as I am about to setup my first pistol with a dot and this will help tremendously.

I knew what you meant about slaving your dot to the irons as a starting point for your zero👍🏻 thank you for the videos

I24gr federal American Eagle is very close to 124 gr gold dot in my VP 9 Thank you for making these videos they have been invaluable to me and many other shooters. I appreciate you sharing your wealth of knowledge

I'm definitely going to try your zero technique as soon as I get to the range with my new RDS. Thanks for the knowledge👍

Can’t thank you enough for these videos. I would be so lost using my rmr without them, and now see how I’ve been using other red dots incorrectly as well. It’s easy to see why people just give up trying, but I’d say they didn’t find your channel!🤙

Thank you. I look forward to applying these amazing concepts!

EXCELLENT AN EXTREMELY INFORMATIVE VIDEO!!!!!! Very helpful and needed.

Great video! Thanks for taking the time! I'm about to purchase a Trijicon SRO, 5 MOA for a Glock 17, gen 5. This is strictly for competition shooting. I would choose the RMR for carry. This will be my first experience with Dots. Thanks for your help! Scott from Dallas, Tx.

Thank you so much man. I love your videos. I’ve been practicing with a pistol optic and it’s much more tricky than I thought it’d be.

Awesome video. Extremely informative and common sense!

Thanks Aaron for the knowledge an how to sight in my Red Dot on my handgun Sir.

Once again Sage Dynamics always puts great content. This Scholar really breaks down the Schematics and the Science ❤ it 🥳

Excellent video as always

April, 2019: "Handgun ammunition isn't that expensive." October, 2020: "We are changing from five-shot strings to one-shot strings." ;) Thank you for this very informative video. I am pretty new to red dots and this helped me a lot.

Great video and informative. I just received my first red dot for my Sig firearm and looking forward to taking your advise here on sighting it in.. thanks and look forward to others that you can help us out along the way to good shooting

Amazing, highly detailed video, thank you

Second time watching this video. It gets better every time I watch it.

Cleared up a lot for me …. i was struggling hard .. took your advice and fundamentals and in few days of practice….laying in some nice groups at 25 yards… Thanks ..

I didn't see your first video but came across this one which helped me a lot made more sense than other vids I seen thanks!!!!

Thanks for posting this video and your video "Why you should never slave your red dot to the iron sights." Your videos were extremely helpful. By habit I had gotten it all wrong. I used the incorrect technique when I shot and placed the red dot on the front sight. On my next trip to the range, I will re-zero the red dot reflex sight and start with placing the red dot on the front sight and then when I bisect the dot I'll move on and continue the sight zeroing process by placing the red dot in the center of the lens window so that I will be able to shot by centering the red dot in the middle of in the window and place that red dot directly on the target.

Just got my first red dot! Exactly what I needed to know

THIS is exactly what I needed...thanks so much. Now I just need to find an optic specific handgun class near me.

New red dot guy. Hit the KZfaq’s before I developed bad habits. This guys series on red dot issues is very helpful. Good job 👍.

Great video on just what I needed when I needed it! I just subscribed! The knowledge you have is incredible. Thanks!

Thank you for the video! Very knowledgeable. I enjoy your content 🇺🇸

I got into pistol red RDS a year ago. I couldn't tell you how many people say that to co-witness the dot to the front sight is the correct way. I never did agree with that for all the reasons you stated. What I like best about RDS on different pistols I own is that the POA and POI is the same for every gun. With iron sights I have guns with a combat hold, center hold and my adjustable sights a 6 O'clock hold which I prefer. With a RDS I use the same hold on every firearm.

Thank you Aaron! I have a new Glock G45 with a 6.5 MOA RMR, taking it out tomorrow Gotta get it zeroed!! I appreciate the video more than you know.

Well said! Made tight - tighter!

Aaron, thank you so much for this video. Lots of great info, answered every single question I was thinking of to zero my RMR equipped Glock 19 MOS. Thanks again, and keep up the great work.

Nice video. Worked like a charm!

Very well made video. Very helpful and informative. Getting ready to zero my new RMR HRS Type 2 onto a G17 Gen4. Thank you for this video. Wasn't sure if I needed to zero at 10 or 25. Also I am going to try the 10/25 yard target you showed, then move out to 25 yards using my carry ammo. I am brand new to running a red dot on a handgun. Wish me luck.

Great information like usual. Thank you

Best rmr zero video on KZfaq!

Great video, brother! I’m excited to up my RDS pistol game after years of shooting rifle and sub gun RDS’s. . . Don’t get old!

Thank you I feel like I have a platform to go off of when I'm zeroing my holosun 507c on my glock 19 mos but I did mill the screw holes so there a little deeper so it will not come loose or move at all I've shot 2,500 rounds and so far so good so thank you earen I really appreciate the time that you take to put out such informational vids man 🙌🏼

Good info. Thanks for the reminder to check your carry ammo. 👍🏽

If I don’t have a sand bag on me I also use my zip lock bag filled with 9mm rounds in it for surprisingly good improvised stability. Great vid as always bro

So much knowledge I had to watch your video at least 8 times...I had a hard time wrapping my brain around the fact of you using iron sites to start off but then magically the red dot appears in the center of the glass. How can iron sights and the red dot both be accurate but yet so far away from each other?...After the first illustration showing you using iron sights you said specifically “shoot using the red dot and keep it in the center of the glass”. That’s where it all made sense. Of course on the eighth time watching your video. Sorry for the long comment but you have a new subscriber and I appreciate all the knowledge.

I zeroed at 12 yds using a bore laser at bench rest, worked really well.

The crimp jump is what I look for in carry ammo, GOLD DOT is very good as far as that is concerned. THANKS FOR SHARING.... Saving lives, money ,and time, one video at a time....

Perfect timing, I’m going to set my new carry pistol this way. Another thing to mention. When ammo was more readily available, I would get a new firearm, I would get 6-8 different brands (same weight) of ammo to see what the pistol preferred. You can then see if that brand makes defense ammo (jhp). You would be surprised how many people run one ammo brand and assume the firearm is inaccurate.

Your fckn great at what you do. LOVE your videos bro! Please don’t stop making them

“Handgun ammunition isn’t that expensive” 2021 enters the chat

I just zeroed my my g19 mos at 25 yards. With 115 grain ammo. Then make impacts at 100 yards. I like that 25 yard zero

Good info. I was confused the other day at the range on how to properly zero the Holosun 509t on my FN 509t.

Just found your channel. Eye opener! Recently picked up a S&W Victory 22 for use as a range gun because of ammo cost. Just mounted a Vortex Venom and really didn't know where to start. I'm thinking this is a less expensive way to learn red dots. I also have a S&W M&P 2.0 that has the slide cut and plates for red dot mounting. I'll be reviewing more of your videos for suggestions on what to get for it. Thanks for your time and no-nonsense info.

Thank you very much for this video!!

For those wondering why the final illustration shows the dot high above the perfectly aligned iron sights, that is because the illustration is incorrect. The front sight should be slightly high in relation to the rear sight. The dot and sights would line back up if the pistol was slightly aimed down. It’s all a matter of perspective based on where the eye is in relation to the pistol. I posted this explanation in another thread: The final illustration is inaccurate because the iron sight alignment didn’t change, but the dot alignment did. The front sight should be slightly above the rear sight when the dot is up in the window. The dot is moving up because the pistol is being aimed slightly “up”, but the eye level is going with the dot. If you use a rifle with lower 1/3 irons, the same thing happens. You CAN perfectly co-witness the irons with the dot, but when actually using the dot, the irons will not be part of the sight alignment anymore.

Aaron great video. Only request would be to have a few shots of your setup on the bench or standing technique for zeroing.

Good info, i've been looking at red dots lately.

The illustrations are a great idea. I've had a few people ask to look through my RMR equipped G19 at some local matches. First thing they do is line up the irons and comment that the dot is below. I try to explain. Still amazes me that people who couldn't imagine shooting a carbine without a dot can't open up their minds to shooting a pistol with a dot. I don't even waste my breath anymore, and exclusively refer people to your videos, whether it's for techniques like this one or tests of various dots.

In my experience, if you carry Federal 147 gr HST standard pressure than you can use speer lawman 147 gr or American eagle 147 gr (I believe they are they same loading - just different brands from the same manufacturer) for the intial zero and then only need to make make minor adjustments with HST, saving a significant amount of premium carry ammo. In the long run it may be worth finding a range ammo that performs similarly to your carry ammo just for this purpose.

Outstanding vid, Thank you👍

Thanks AARON.

Another amazing banger.

Great information, thank you

Great info for me as I am getting my 1st RMR for. Glock very soon.

Great video took me a little bit.. but i have her down now… Thanks for the video.. 1 1/2 inch groups 25 yards .

thanks for the lesson. I'm new to shooting and this helped

Excellent video.

My go to channel 👍

Thank you this will hopefully help ALOT i got frustrated and took my reflex off because i couldnt figure out sighting it in

You Rock Aaron ! Liked/Subscribed !

You’re the man !!

Thanks Aaron...

Thanks Allen.

I hope a lot of newer shooters Subscribe, Like, Share, this gentleman provides a TON of great information for the handgun community for free HE KNOWS HIS SHIT

I put 1" orange stickies on a target. Walk up to 3yds and shoot a few rounds (don't bother cowitnessing). Make COARSE adjustments. Check with 1-2 rds. Make another correction if necessary. Back up to 5yds, recheck. Adjust if necessary. At this point I'll back up to 15 or 25 for my final zero. The final zero I do just like you, from a flat top using a bag, 5-10 rd groups. The biggest difference is dealing with the frustration of trying to sight in a red dot from 25 at the beginning. It's hard to even see the hits at 25 (binos are good to have). Anyway, I tell people just start at 3yds and work backward. I'm convinced its quicker and less frustrating.

Thanks for the info...

Thank you. Love your videos. Faithful subscriber.

Great Video

Just returned from zeroing my 10mm, or at least attempting to zero it. It's close, but still needs work. I was getting tired and sloppy. Wish I had found your video before I left.

Watching these videos help again and again. Where are his recent vids?

Thanks for the info. Looking at getting my first pistol optic for ccw.

I recently purchased a new firearm with a red dot sight factory installed. The instructions with the sight said that it was zeroed from the factory. I set up a target at 25 yards and fired 3. Checked the target and found no holes. Got a larger paper target. The gun shot 12 inches left and 8 inches low. I called the gun company customer support line and discussed this, and was told I had to co-witness the dot and the iron sights.

"you can't fix bad mechanics with equipment" Spoken truth

Very helpful

THANK YOU!!!! Just picked up a SIG P320 X carry with a factory Romeo RDS at a steal right before the shtf with the Chinese flu and need to zero the thing - your video is Just what I need, especially now that ammo availability and cost are in the critical zone again!
