Dont think many people know about this product so thought id share. Nic Taylor makes replacement followers and mag springs for many .22 pistols. I bought some for both the M&P22 and 22c pistols. 22 now has 15 rounds and the 22c now can hold 14. you will lose the load assist button which also functions as the hold open on last round activation. no biggy to me in a plinker pistol. ive been using a .22 Lula that works pretty well. ive ran at least a brick thru each gun with these new internals with no issues.

they run $12.99 plus shipping.

Thanks for the heads up, but I am using my M&P22c as a trainer for my young sons, so I need to keep the last round hold open. Get me hold open and 12 rounds and I would be all over those. For a pinker they would rock.
