I mentioned in another thread that I am considering adding a .40S&W to my slowly growing community in the safe. I visited a LGS, where I had the opportunity to examine an H&K USP .40 Compact, which, of course, fit me like the proverbial glove. If I were to continue looking at the H&K's, what should I be looking for? For example, with SIG's, I would look closely at the rails.
As an alternative, and to stay with the calibers I currently shoot, there is the H&K .45 Compact (or the USP .45 Compact).
If I were to acquire one, it would initially be a range gun. Not sure if it would become an EDC.
What are your likes and dislikes for either of these two choices?
