+5 round magazine bumper - TANDEMKROSS Wingman Extended Magazine Base Pad, Walther P22

Easy install, even tho there's no detailed instructions. Good quality. I've cycled a few rounds through them without fail. It is a bit more difficult to load the magazine now with the slide lockback removed :( worth the trade off for 50% more capacity :) the extra finger room is awesome as i have man sized hands. I think it makes the gun look better too. I accidentally bought more than i needed, i didnt realize 1 package accommodated 2 magazines.
