I have a USP 45 full size I ordered a 12 rd. mag. for it and it don't seem to fully seat in the pistol it locks in ok but theres a gap between the floor plate and pistol handle. Its a factory HK mag. and was pricey it won't feed right unless I push the mag. up when I shot the pistol not to easy to do. Is there any way to fix this problem my 10 rd. mags. seem to work ok. There's about 1/16 of a in. on the bottom of the 10 rd. mag. and about 3/32 of a in. on the 12 rd. mag.
