I am selling some GSG/SIG/PRO TSC 1911 22LR +4 High Cap Followers, you take out your old magazine follower and pop this one in and it will give you a +4 round capability. I am also making some other things including steel guide rods and some metal butt pads for mags that also give a +1 - so could boost you to 15rds
