Great video. Laugh Out Loud I'm the guy that went from 80 grit-1000grit wet dry sand and then used flitz on the polish wheel on the Dremel to blend it in. But I found a secret trick! After all your sanding and polishing, if the color of the polymer is still slightly off, rubbing a bit of Bow String Wax on the surface of the cut area blends the colors and brings it much closer to matching. really seems to finish the overall job and appearance and feel. Using your finger for friction try to just slightly warm the area, add a tiny bit of the wax, and rub it in. I did 2-3 applications and it really helps, Hope this helps.

Best undercut tutorial I've seen yet. Thank you for the video.

I did this tonight on my kitchen table, just the way you drew it up. Came out perfect! Thank you soo much for this great video!! My "Glock Knuckle" pain is totally gone getting rid of that nasty bump.

Never been a big fan of the under cut trigger guard, but you made that look so simple yet functional. Good video, nice work.

Wow this is the best video that I've seen on undercutting a Glock on the internet. It amazes me how people spend so much money sending their guns to a gunsmith to have it undercut when you can do it at home just like you did. Thanks for the video John.

A tip I posted elsewhere. Between you heavy work, let the polymer cool down to cold. The friction goes bout 4mm deep. My very first job was a G19 and it came out perfect. There are smaller grinding drums, John. That's what I used. Took me an hour and it's perfect.

Thanks 4 the video. I've done tons of research on doing this but ur video finally gave me the balls to do it in my older G22. It turned out great! I will be attempting it on my newer G43 next.

Placing your firearm in a vise to hold it steady is always the best way to do modifications like this, thus increasing your likelihood of a successful professonal looking job.

Followed everything you did and my double undercut came out perfect! Thank you so much!

This was an awesome tutorial and gave me confidence to my own. Excellent video. Thanks!!

Watched the video several times, then watched it as I replicated the process. Worked great! Thanks a ton!

Hell of a job for the available time. Thank you for all the tips.

You really helped me out with this video, thank you

Thanks for the video. It has made such a difference in the feel of my Glocks. Still need to shoot it at the range. Cant wait

Best video ive seen on undercutting so far, Ive been wanting to do this to a 2011 plastic grip , nice work

Good video. I taped a small piece of soft, sheet brass on the handle near to where it joins the trigger guard to prevent damage from the grinding wheel. I also covered all the gun openings, the magwell, etc. to prevent the entry of debris. A few minutes of preparation keeps the gun clean, debris-free, and avoids the need to spend more time cleaning the gun after surgery.

Thanks for showing that. I have been wanting to try it.

Well I know 3 glocks that are going to get done when I get home ! Thx for the video !

THANK YOU for your excellent demonstration under cutting a glock trigger guard!!!!

Thanks for the vid John, I really need to do this to my G32!

Just the video I was looking for,thanks!

Hey John, did the under cut on my G32!!! So much better. 👍🏻 Thanks again!!!

I find that removing the top 'finger bump' from the grip works well for me. That bump forces the finger into the guard.

Great information, well done, thank you!

you dont give yourself enough credit, I would be happy with this job even if I paid, nice work

Thanks. Good video with lots of info and great presentation. I learned alot.

thanks for showing the polishing aspect... and yes your right.. it burns like hell of it gets in your eyes!

NICE!!!! I like your style.

I have the same Talon grips, I removed mine before I did the undercut. once finished I replaced them and used a hairdryer to form them back into place. No issues and as good as new. I used the lowest setting on my Dremel with the coarse pad and finished with the fine pad. Turned out great.

Very Cool…I’m doing both of mine today, thank you.

Thanks for the video. Now maybe I can like my Glock.

Really good stuff. Happy I subscribed!

Eye pro! Thanks for the vid, good instruction

Good work, thx for sharing.

Ahh 60fps...soo smooth :-) Great Video!

Looks great

Thanks nice vid. I'll save this for reference when I undercut my Glock 42 and 43

Outstanding video 👍🏽 I always send mine out but I didn’t it was that easy. I know what my next project is .

Woah auto stabilization sickness lol. Great informative video, simple and straight to the point. Thanks

Very nice work 👌

Awesome video, thanks!!

Awesome video !! Ty

Thanks for the excellent demo. I'm trying to get my nerve up to start whittling on my pistol. 🤣

VERY NICE JOB. Fingers a lil cramped on my 19. I Believe that will solve the problem. Thanks

Amazing

Thanks for the help .. 7 years later

Nice work... I'd consider that finished and would be very happy with it...

Excellent...!!! 👍🏼👍🏼👍🏼

Subbed Mr. Horvath, thanks for the great video, going to do this tonight!

Good video. Those Dremel sanding drums cut better, and last longer if you use an old toothbrush to clean them as you work.

Thanks for the Video!

Great video I did my 19 my 26 and my 17 my question have you ever rounded off the front of the trigger guard to get rid of the squareness?

great info

I used metal foil tape to protect areas I wasn't working and finished it off with rubbing compound. My middle finger knuckle is much happier now. Using a vice made it easier to get things even and then I hand held it for the radius work. Glock knuckle no more.

My Glock is unique now. I dremeled the square trigger guard into a rounded one!

Good vid

one very important mod is to radius the forward part of the trigger guard... that is the vertical piece set towards front end, and create relief on the inside portion of the guard.... where the tip of your finger touches... hits... that it is momentarily blocked if you need fast access to the trigger. it should be melted and relieved just a bit or more so your trigger finger slips right by it without a sudden hangup ... albeit however brief that may be.. it is still one more second you lose when attempting to quickly find the trigger.

There are some I’ve seen that look really nice and shiny. How do you get it like that?

Shoutout to Marty

I'd recommend a 240 grit thinner Dremel bit though

Nice!

Another good idea too is to wrap with electrical tape, work at it, once you feel comfortable, remove it, then work your groove, And like you said, if you mess up just get another. (if you're able) then try again. Dope tutorial tho.

Ever used a bench vice.? Make sure you either tape the points of contact or use rubber feet...

I need to get myself a dremel so i can work on my Glock 26. Went to a private bay to practice my holster draw for two hours and got a nasty blister. It was my first time shooting the 26. Never happened with my G17 so it might just be the lack of pinky placement.

Excellent under cut work. Did you use nail polish for the engraving or was it heat resistant paint?

Doing another 26 double undercut, index stipple an some polishing in tha morning. Wooooo lol

Sir do you have any idea how to polish the undercut back to its original gloss? Thanks in advance sir.

anyone have any ideas for me, i added an x300 n i feel like my grip is all messed up. i feel like i should put one of these in the last portion of the trigger guard, like a reference point. im new to shooting pistols n im just going by whats comfy n gets me shots but i know my grip isnt "correct". anyway, is the trigger guard reference point a good idea? i stippled there n its just not good enough. the rest of my stipple is perfect, but i feel i need something more on that trigger guard.

i know this is few years old but i wanna know what is that trigger called? it look nice

You DO have some good tutorials. Do you normally use a vise? It would give you a 3rd hand, so to speak. And for people that might do it the first time, like me, I think I'll figure out how to mark it on both sides so it comes out "even" looking on both sides. Also, I wouldn't want it to look any more polished than the stock texture, or close to it, but thats my preference. For people doing it the first time, also, if you start it and feel like you're not getting the results you want, stop and then let someone else do it before you go to far to be able to fix it. Not that big of a deal, like John here says. Hell, I might even go so far as to give the "Glock knuckle" area a concave shape in both directions, side-to-side and front-to-back, so theres kind of a crater shape in there... idk, might just try the side-to-side first and see how that feels. Like I said, decent tutorial.

Exactly. 💪🏾💯🙌🏾

you should have used blue painters tape to block all that plastic dust from enter the gun and especially the trigger openings... that tiny dust can make a giant problem.

Nice

how many volts is your dremel?

I was looking for a tutorial on how to do this. Same last name lol

can this be done the same way with an m&p 2.0?

What does the Flitz do anyway???

Sausage fingers! Amen, brother!

Can you do a video of an double undercut

It burns when you get it in your eyes hahaha

I got a little overzealous with mine on full speed using a diamond drum, now I have a window into my maxwell and my trigger guard 🤷‍♂️ but I can get real high up on there now haha

Awesome video, grateful. But, what I would like to know is how you get the lettering white on the slide

Nice job John, your video made me do it. Greetings from Hungary :)

Nice work. My middle finger feels real uncomfortable on the trigger guard if my g21 sf. Wonder if this is the fix.

Looks simple enough, yet I think I will pay someone to do it, that has done a few or a 100.

I wish i could train enough to get a glock knuckle

Nice work. Curious, does the talon grip allow room to change out backstraps or did you put the backstrap over the talon grip?

Thanks for the video. I think it is important to show clearing the weapons before any work or handling. Thanks again.

Why does glock not make the undercut from factory if everyone is always wanting to undercut?

Your voice sounds just like John Candy's.

You see where people have chewed through the handle. LoL

I always wanted a Glock but when I got one, I couldn't stand the trigger. Why does it pinch your finger all the time?

I'm doing it

I have pretty skinny fingers compared to this guy. You think i should go down in size of the dremel bit or would it not make a big difference?

The more you do it the easier it will get of course.

👍

how'd you get the white lettering on the slide?

Should just move it forward, cutting it deeper doesn’t help near as much

Just got my first Glock. 43x. The issue I'm having in addition to the one addressed here, is my trigger finger rubs on the bottom INSIDE of the trigger guard while pulling the trigger. But not all the way across the guard. Just down the center. It looks like I could use a similar process to the one demonstrated here to slightly hone out sort of a trench down the center of the trigger guard to fix this. Maybe just a little would make a big difference? I suppose I would have to find a narrow enough wheel to do it.

You talk as if you buy a glock every couple months lol
