Trigger Guard Undercut

ByronF · May 06, 2017, 15:39

Got my first Glock: a G23. Easy to understand dislike for finger grooves, and today teied the trigger guard undercut modification. Originally I'd say my fingers landed about 1/3 finger width too low to mate to grooves. MUCH better after undercut. Dont even notice grooves now.

Have a couple of G23s myself, Gen 2 & 3. How did you do the mod?

Watched a few DIY youtube videos, belted down a stiff glass of beer for courage, sparked up the Dremel. My variable speed Dremel is now always WFO but that melts and rolls plastic so dont do that. Go slow so you are abrading it off, not melting and smearing it. The plastic is never the same and ends up with a skin of smeared plastic laminate. I sanded theough that skin when I was done, but really just need a new Dremel. Or at least a replacement rheostat if available.

Startsd with a coarse roll, then switched to the finer one. The rolls I have are 0.600" diameter. In vids it looked like smaller rolls. But the 0.600" about matches the radius anyhow.

After Dremel work was done I hand-polished the area with 600-grit wet sanding paper, used dry. Did this until uneven areas were blended smooth. Final texture is like satin, kind of a rubbery feel but not soft. I buffed entire bottom of trigger guard so the transition isnt noticeable.

The undercut will really help with recoil control too!
