I love my H&K USP Compact 45 but I have one problem with it. My mag changes are too slow. No matter how hard I train to get fast at it I just am not happy with my speed . I am not sure if my thumb is to short or what it is. I tried using my trigger finger and I am still not fast enough. I was thinking of trading it for a Glock 30 but thought I may try an extended mag release first. So how much difference does the extended mag release make? Does it make it so you don't have to shift your hand as much? Thanks in advance.
