View Full Version : Glock trigger guard undercut.
I need to get the trigger guard on my glock 19 undercut. Who would you guys recommend ?
The only place that would do it nearby is going to cost $150. I also need the mag release on the gun trimmed down a little bit too because it is a gen 4 and the mag release button is huge.
It's just plastic.
Sharpen your pocket knife and whittle off what you don't want, then clean it up with some emory cloth.
Pocket knife? What is this, the 1880s? Just kidding, bro.
Option 1) Get a Dremel aka the Wonder Tool (ok, only I call it that). You can use the grinding stone to do this. Put it on low and go slow!
Option 2) Or for better results but more time consuming, pick out a round wooden dowel close to the radius you want. Put the frame in a vice, wrap the dowel in some sandpaper, and slowly go back and forth keeping the dowel even.
For either Option 1 or 2, use a buffing wheel on the Dremel, or some emery cloth if you don't have one, and polish it up. If you use the Dremel, do NOT stay in one area too long. Cranking the RPMs up is fine, but if you stay in one area too long - the frame will begin to melt from the friction. And it's a bitch to clean it up nice once it's melted.
If you buy a Dremel, get the corded version with micro adjustable RPMs. The cordless, macro adjustable RPM version is a turd.
Hope this helps.

To get it to look its best, use a Dremel sanding wheel. Once you get it close to where you want it, use a buffing wheel with a little compound. Be careful to go at a slower speed. If it heats up to much due to friction, out of nowhere you'll take out much more than intended.
Here's one of the M&Ps I've done.

This is a different one where I rounded the sides a bit more and didn't cut it out as much. Sorry these are M&Ps, but I'm content with my Glocks. $150 for just undercutting the trigger guard is a bit much, it's not a 1911.

The dremel option is intimidating. I have never used one on plastic before.
I think I can make it work for the mag release pretty easily.

No reason to be intimidated. You totally control the speed and pressure. You can hover it just away from the nylon and not take off anything, then gently work it in to barely scrape the surface. :)
It's pretty funny, when doing it to remove the Gen 3 finger grooves a few months ago (I used the sanding drum), I got it warm enough to smell the nylon - smells exactly like 550 cord. Hilarious.

I use a 1/2" wooden dowel with 80 grit sand paper wrapped around it. Once I have it close, I switch to 120 grit, then 220. After that I use a buffing wheel on my dremel to finish it up. You could stick with the dowel, as I did in the past, just keep going to less course grits, like 600, etc. The first 3 Glocks I did was with just the dowel and they turned out really well.
I undercut the guard and cut the finger grooves off of my G19 with a rasp that I got in a hardware store for 10 bucks. I fired a few rounds, locked/cleared/field stripped, then used the coarse side to quickly remove the offending parts. Lather, rinse, repeat until I got it just the way I wanted it. Then I used the fine side to smooth it up a little.
My crude methods have another benefit. There's a guy at my range who's just gotta comment on things that he knows almost nothing about. He was watching over my shoulder as I shot and was about to say something about my group until I attacked my G19 with the rasp. As he looked on in horror, I said, "Hey, it's not like it's a 1911."
He hasn't spoken to me since.
YMMV.
Okie John
I would be real careful with a Dremel on a plastic gun. It takes material away fast. For a first timer, I would go with the dowel and sand paper idea first. I use Phillips screw drivers with some 180 grit or so wrapped around the shaft of the driver. When you've got it about where you want it use a BBQ lighter to gently scorch the area. This will burn down all of the fuzzies sticking up. Then wipe the soot off with a towel and you should be good to go.

Do you want this done to alleviate "glock knuckle" or to get a higher grip on the gun?
I would like to alleviate glock knuckle. My middle finger is sore after shooting the compact glocks.
My middle finger on my right hand is pretty beat up from an injury from years ago and it still hurts after shooting the glock for a while. The finger swells at the joint sometimes after long shooting sessions with a compact glock because its right against the trigger guard.
Did the undercut to the four Glocks I have here now and it made an amazing difference in comfort on the middle finger. I also get rid of the finger grooves as well.
It's well worth it.
The undercut has made a big difference with my G21SF.

Really impressed with that rounding of the trigger guard. That's the one thing I've not yet attempted.

In that case you may want to consider just flattening out the sharp corner of the trigger guard on the spot that hits your knuckle. That's what I did, and it feels great.

Big +1, another here that did this. 5 minutes with a couple files gave me a significantly better feeling Glock. Let me know if youd like a picture of what Hayden has described.
Like some others have posted, if it's your first time, stay away from the Dremel.
I started with 120 grit 3M "Sand Blaster" sandpaper (the purple colored stuff at Home Depot/Lowes that is anti-clog) wrapped around the cylindrical shaft of a ball point pen. Slowly knock down that protrusion and re-test your grip constantly. Then use some 600 grit and 1500 grit to really smooth things out.
I've done many of these now and always begin with a Dremel, but only because I know what endpoint I'm trying to reach. I still use the 120 grit sandpaper wrapped on the pen to achieve a uniformly level surface because, oftentimes, dremeling leaves ripples, especially if you're removing a lot of material.

I have a tutorial with pictures for the rounding process. PM your email address and I'll send it to you. It's not difficult.

You're talking about Hatfield's huh? FWIW the $150 includes:
Includes any combination of: undercutting trigger guard, at-ready cut, finger groove removal, grip reduction, any area of grip stippled including forward portion for "gamer" grip and two magazine floorplates.
Though that still might be a little high? Idk, but I wanted them to do mine eventually, along with the rest of their Vanguard package. Now I may just have some things done a la cart, but still.
The undercut would be a better modification for me. The Glock knuckle sucks but I also feel like my fingers are really cramped when gripping this pistol.
I don't really need every thing on the Hatfield package but they don't list prices of individual modifications. The grip on the Gen4 19 is fine in terms of grippyness.
I like the idea of using the dowel because I can go slow and see what happens. I might stop by Hatfields one day to see if they have any examples I can hold of their modded glocks.
I got my kitchen knife steel, wrapped it in 60 grit sandpaper to the diameter I wanted (slightly larger than my finger) and sanded with that. Used a standard sanding block to make a nice gradual transition from the under cut to the bottom of the trigger guard.

I used the method many have mentioned... I bought a Dremmel tool, Soldering iron (you can change the tip out with a similar diameter screw, and texture the screw to any style checkering or "stippling" you prefer). I opted to use the standard soldering Iron tip, and just used it horizontal (since i figure this allows the most relevant grip to fighting with a pistol). I have made 10-15 modifications to this pistol since i started and continue to tweak little things here and there. Honestly I think its THE BEST grip I've found on a Glock without going so CRAZY that Appendix Carry Inside the Wasteband becomes dangerous or uncomfortable. I added a unique Magazine modification advocated by a good friend and firearms instructor Paul Gomez. He mentions in a few of his youtube videos that clearing Double Feeds with a pistol becomes a HUGE issues one handed. So he advocates relieving the front strap of the Glock mag well enough to hook the magazine baseplate on the belt and RIP the mag out IF such an issue ever presents itself. I went with a minimal front strap reduction, added the side half moon cuts (figured WTH?!), and then smoothed it all down with my grinding bit, and then used the felt tip dremmel bit to fine tune/smooth everything out to factory specs. I've been VERY pleased with this configuration and used it in a couple pistol classes and training sessions since and find it to be idea for my needs. I left the sides of the gun smooth to keep from chaffing me when I wear it AIWB, and because i dont see the need for them to be all 'narly'.
You notice I also threw some stippling on the position my trigger finger rests on the side of the frame or my support thumb when shooting two handed. Helps me get a consistent 'register' everytime I grip the pistol with my trigger finger and my support hand.

Holster pictured is the new Raven Concealment VG2. I LOVE IT for appendix carry.

They have one in the shop that they've done work on, I'm sure they'll let you hold it. IIRC, its a G22 race gun.
Cold Bore Customs (http://www.coldborecustom.com/Services.html) does the undercut for $10 plus $10 shipping. I don't have first hand experience with Lane's work but I haven't heard any complaints. I plan on sending my 19 to him soon.
I did mine myself. It was really easy and only took a short amount of time. I used a marker wrapped in sand paper, sharpie or dry erase type of some sort. Same concept as using a dowel, but I just used what I had on hand. I just used really rough grit at first to knock out the rough idea of what I wanted and then went finer and finer. I just kept putting pressure up and to the rear of the frame at first to get a higher grip and then went forward on the trigger guard to get that gradual slope to alleviate Glock Knuckle. I used 3 different grits of sand paper and then finished it off by hand with some of that green Scotch Brite pad stuff. It kinda polished up the rough finish at least to the point that it didn't stand out. Looks pretty factory now and really made a difference for me as far as the fit of the pistol to my hand went. That little bit of relief up there let my fingers line up with the factory grooves. My hands fit the Glock 17 just right, but the 19 had less room for the first finger, this solved that problem for me. I think it was well worth the time, and I'd say you should just go for it on your own, it's so easy a grunt could do it...lol.

Now I just need to get the nads to go after it with a soldering iron...lol.
