Not a Glock but my 1911Sc SW Commander will give me a worn, spot at the web between my forefinger and thumb. It will take a match to do it, so it's not an immediate cut. I put a bit of tape in that area and it's fine.
No problems with any Glock except when I foolish cross my thumbs. Why - duh - it was a inside the car scenario and I had to shoot from the right side. Being left handed, I thought it would be better to switch hands (stupid). Well, not being totally in automatic motor control I took a stupid two handed crossed grip. Ouch!
Learned that lesson. If I have to shoot right handed, I usually shoot one handed. Rationale in part is that this would occur if my left dominant hand is out of the game.
I dry fire a great deal like that.
