What you have, if I'm not mistaken is a Stagger Feed(A.K.A. SF) action. The action screw spacing is the same on both the Center Feed (CF) and the older SF. With regards to the bottom/ mag port of the SF, the opening is machined differently than the newer CF action. This poses problems with factory magazines. I personally can't help you with aftermarket magazines that may work with SF but someone else might be able to. There are several in business that make them and I think that maybe the AICS magazines work for both but i am not sure.

EDIT: CDI can provide you with a tactical setup for about $306 for a 5 rd setup and $356 for a 10rd setup.
