Made this look so much easier than it is. You can tell he really does this

[@tonyromano6220]

Modeling skills! I am still afraid to try this! Need to setup vice. Too many hobbies!

[@kev8370]

“That’ll be $200 dollars”

[@gunsandgaragegear601]

So the double undercut is if like you’re wearing gloves and your finger is farther forward? Because otherwise I don’t see a need for anything more than a single undercut where your support hand pointer finger is

[@notagunchannel]

Some people have a very high grip like myself. That gives a little slot for your index finger on your support hand to sit in

[@mrmotonut2465]

I have to assume you've never held a glock with the undercut vs not undercut. The difference is HUGE

[@shaqparker7025]

Undercut was the FIRST mod to my Glock 19!!!! Makes a big difference

[@freebeard7361]

I genuinely want to know, what's the point of this?

[@shaqparker7025]

@@freebeard7361 adding an undercut gives your middle finger more room so you can get a higher , more secure grip on the gun. People often make changes to their stock Glock frames to be more comfortable for them. Stock Glock frames can be a lil slippery imo

[@markreed2576]

@@freebeard7361 shoot a G19 and you will get Glock knuckle. It’s not fun. I dremmeled mine before I ever shot it again. Makes it a lot more comfortable and easier to get a higher grip on the gun. This helps for accuracy and recoil control. The video shows me how to clean up the tool marks. I’ll do that next. I didn’t remove any material from the trigger guard forward of the grip radius just the radius.

[@kevinc.cucumber3697]

@@freebeard7361it fucking hurts my middle finger. My finger is bruised and skin is ripping off. It’s personal preference, but the trigger guard is way too low

[@vondutch960]

Why use a glock 19 if you're not comfortable with the grip. Instead use a glock 19x or a glock 45.

[@abcthings1122]

Great work. Beautiful video. My g23 has the same cuts.

[@johnk7898]

Did you smooth out the rest of the trigger guard after the video, or did you leave the texture and the mold stamp.

[@Andrew_Dominik]

I understand why someone would cut the spot where your middle finger rests but why add the ridges further along the trigger guard?

[@StickysituationTV]

Appears to be a dremel wand extension and a sanding wheel. Grit on the sandpaper should progressively get finer throughout the process.

[@jojodancer1743]

Ahhh the life of a glock lover. Buying aftermarket parts to bring the weapon up to speed. Making snarky comments comparing your highly customized gun to other people's stock guns. Nice quiet mornings grinding your gun into a different shape and basically finishing designing glock's gun for them. Delightful times. Glock is "the best". Lol

So there’s a magazine in the gun with it pointed in the guys direction while he’s working on it at the beginning. Is that bad? No trigger.

[@veediohs]

It's just a bare frame. No slide on it and the magazine is just dropped in there so the vice doesn't crush or deform the grip, it's not actually seated fully.
