Yesterday I traded a P3AT for a very old P11. I thot this would be a good trade for me as I had some old left over Ram line and Smith mags in the war bag. Gun came with one 10 round mag. It is the only one that will seat up and lock in to the gun. None of the Smith or Ram lines will lock in. I always heard they would but they sure won't on this one. What gives do y'all think???
