    Glock Knuckle and Potential Fix

    Post by Tennessee Jed on Tue Nov 18, 2014 12:57 pm

    Lately I've been spending more time with Glocks. Giving my wheelguns a break for a little while. Before I go back to revolvers full time, I want to get the same level of comfort and familiarity shooting Glocks as I have with my revolvers.

    With the extra time spent firing and dry-firing, I've noticed the skin rubbing a little raw and a callous developing on the side of the knuckle of my middle finger on my shooting hand, the part that makes contact with the underside of the trigger guard. I did a little research online and learned this syndrome even has a name, "Glock Knuckle".

    What's happening is, there's a little cutout where the trigger guard meets the grip, which lowers the pistol deeper into your hand. Cool. Makes for a lower bore axis. However, that leaves a little hump in the trigger guard that contacts the front of your middle finger, and it rubs a little hard on your knuckle if you have long fingers. Also, the polymer at that spot is a tiny bit rough. I never noticed it before because I've not spent as much time shooting my Glocks consistently as I have lately. It is more of an issue for me with full power 10mm and 40 S&W ammo than a 9mm.

    So now what? There are plenty of places that will reduce that hump for a fee. But what good is a plastic gun if I can't modify the shape myself? I took some sandpaper to the hump and smoothed it down a bit. Then I used progressively finer sandpaper to make it a nice, smooth surface. That section is now smooth as glass and MUCH more comfortable

    Haven't shot the modified Glock yet, but I'm already feeling a huge difference in comfort when dry firing. I'm very anxious to get to the range this weekend and try it out. Will let you all know if it was a good idea, or just a stupid idea that I will regret.

    I had the same problem with my g27 when I injured my middle finger middle knuckle. I ended up selling my g27 after that, and started carrying my g19--which didn't have the same problem for me.

    Yup, that's the idea. Rounding off the edges of the "Block".

    I have since put about 100 rounds through the 40 S&W, and about 150 rounds through the 10mm. The fix worked like a charm. No bumps, abrasions, or the like on the inside of the middle finger knuckle. Looks like this will work.

    It's a little busy round here right now, but I'll try to post pictures soon.
