Identify this mag
 

Hey everyone,
Picked up my beautiful Colt 1911 Rail Gun and with it came two 8 round magazines and I'm trying to determine if I have wadcutters or hybrid mags. I think wadcutter.

I think you may find that to be a Check Mate mag with their "Hybrid" feed lips. However, they would normally have their logo stamped on the side and/or bottom.

I think it's a checkmate mag because there is a little "c" on the base of the magazine, top right corner. The patent numbers don't help me because based on pictures the hybrid and wadcutters have the same patent number written on them.

I think that patent number would be just for the follower & I don't know if they make their own followers, or buy them out. The lips appear to be their Hybrid lips. The Check Mates I have all have a 'Knight' chess piece as an emblem on the side of the tube or on the bottom plate.

If yours doesn't have the emblem, maybe it could be a GI issue mag?? I'm not sure how to identify them & I am told there are fakes out on the market.
