PCC competitors rejoice! The Taylor Freelance Extended Magazine Basepad adds a full 10 rounds to your 32-round Colt SMG-type magazine. Adds 10 rounds, reaching 42+1. Notes:Colt SMG mags come from many different manufacturers. Colt offered at least two major types - one where the floorplate slides on from the front, and the other which slides on from the rear. The Taylor Freelance Extensions are built to work with both the front-mount and rear-mount styles. No matter what type you're starting with, in all cases the TF retention screw should end up on the back of the magazine.
