Star Super B 9mm Luger 1 magazine. Bought this years ago at either Aim Surplus or Classic Arms. Typical shape for these. This one is decent. Very similar to full size 1911 45 but in 9mm. Runs fine with all ammo I tried - steel case, aluminum case and brass 115gr. Im sure 124 grain would run fine as well. FTF, must be WI resident, prefer CCW holder, no felons. Must be legal in all regards. Cash, no trades. Thanks
