    Extended color plate adds grip real estate for us with large hands.

    I’m cursed with wide hands but short fingers. Grips often just don’t fit right for me. However I found a deal on a USP that I couldn’t pass up but the thing never felt right. Just not enough grip to comfortably fit my pinky. These extended floor plates fit the bill nicely. If I buy any more mags the first thing I will do is change the floor plate out. Now I just need options for the damned ban-era ten round mags.
