I recently bought a G-23 (gen.3). This is my first compact Glock. I have pretty much all the full size models, and just never really had use for a compact model. I carry a HK P7 PSP, or a 1911 commander, for carry purposes. Well, I was offered a great deal on a G-32 with a Storm Lake .40 barrel included. Taking to the range 2 times in the last week, I have developed quite the sore knuckle on my middle finger on the strong hand. I googled it and sure enough, found the name "glock knuckle." I found one thread on another site that suggested using a 1/2" dowel rod and sandpaper wrap and start filing away, eventually using a dremel and fine file. I was hoping I could get some of y'alls ideas or methods you used to get a relief in the rear of the trigger guard. I mean, I understand the object is to recess the area as Colt applied to their 1911 "enhanced" model. I am curious how you did yours and with what tools.
