Please forgive my ignorance. I have been looking for a full-size 9mm USP for several months. I live in a free state where I can have 15 round magazines. I have found a USP that comes with 10 round mags ( 81000309 USP Variant 1). Is the difference ONLY in the magazines? Or is there a difference in the pistol itself that prevents 15 round magazines from being used? If I buy the 10 round package, can I simply buy 15 round magazines and use them interchangeably?
