M&P22 14 round


Recommended Posts

Factory CA mag = 10 rounds

Factory STD mag = 12 rounds

Aftermarket mag = 14 rounds

How?  Pull the base pad.  On a CA mag twist the shiny milled metal stud off the internal base piece...that brings any 10 round mag up to 12 rounds.

Grab a Dremel and slice off 1/4" from the spring stud located on the follower, then grind a little less off the spring stud located on the internal base piece = 13 rounds + 1 = 14 all up.

Mag functions 100%.
