Absolute garbage. - ProMag Kahr Arms K9, P9 / E9 9mm 8 Round Pistol Magazine

Bought two of these, took me awhile to try them out but when I did - first time I inserted a loaded one in my pistol and dropped the mag to check how it functions, every round in the mag flew out of it and hit the floor. Tried putting both loadedmags in a mag carrier, when I went to pull them out both ejected multiple rounds. Will not buy mags from this company again.
