Just bought a Gen 3 Glock 23, and the opening on the grip bothers me. I know Glockmeister has grip plugs for my gun, just curious if there was actually any functionality in the design choice with Glock leaving that part of the grip open.
If your not gonna be doing any water landing assaults then slap one in it. I have them in mine , no issues though 14 years of ownership. Pearce makes the best fitting one I've always used.
I believe it's there for many reasons as. Stripping the mag out better, to remove water out from being submerged. Venting air ..I've heard that here before too. Someone will along to give the technical version.
