GOOD-bye finger humps (Gen 3 Glock 23)
Before buying my Gen 3 Glock 23, I had never shot a compact Glock, only the G17. After owning it for a while, I just couldn't get past the way the top finger hump sat under my middle finger instead of between fingers.
I have invested too much in this one to let it go: holsters (CBST, Remora, Blackhawk), night sights (Tru-Glow TFO's), GlockTriggers.com Guardian, and extra mags. And... I shoot it very well.
I was going to send it to an expert to reduce the grip. I decided to do it myself. First I ground off the humps with grinder. Then I used sandpaper over a period of a few weeks taking off a little at a time. I also slightly undercut the trigger guard where the middle finger rests to be able to grip it a little higher. Right now I have some grip tape on the front strap while I work up the nerve to stipple it. I love the way it fits my hand now.
I took it to the range at my LGS today. While I was there I checked with the Glock Armorer to make sure I haven't taken off too much before I stipple it. He said he thinks its fine to stipple it without weakening the frame as long as I don't go very deep.
Here's a picture of it now. I will update the thread after I stipple it next weekend.
