well, I don't work for Galco, but I'll offer up my experience in the matter, having looked for a holster for my HKUSP 45. There are at least three different holsters for the .45 models... USP, USPC, and some other model which I'd never seen. Well, being that I have a USP, I thought that the C version would work but be a little shorter. Nope, the trigger guards are different between the USP and the USP compacts. I'll be interested to see what I need to get as well when it comes to a fine "Galco" holster (brown nosing not intended).
