These magazine modifications are for the Smith & Wesson M&P 22 made by Walther. With this magazine upgrade you can get 15 rounds in the magazine. This modification is not permanent and easily instals by removing the factory follower, spring and spring retainer. Insert the Shockbottle follower, new spring and the included spring retainer and slide on the factory basepad. Load up and you are ready to rock and roll!

Please note that with the shockbottle follower, you will loose the slide lock to open on the last shot fired (the slide will not lock back on an empty mag upon firing the last shot).
