I've really come to like the USPc pistols I've gotten this year. As I mentioned in another thread, I was thinking about getting a Gen 5 Glock 23 when they came out. But then I got the USPc in 9mm several months ago. Excellent pistol! Then on Armslist I guy was selling a complete USPc upper in 40 S&W. I found out the lowers are the same so I purchased it and then later on got a 357sig barrel from Rim Country Mfg. Not that I'm a big 357sig guy, but I wanted the entire platform to be a 3 caliber-in-1 pistol. Just excellent all the way around. So I'm pretty much not interested in the Gen 5 G23 anymore as the HK USP just offers way more of what I prefer in a pistol.
As far as the Sigs, like the HK's they are simply quality pistols. I don't have a ton of experience with Sig but I did have a P226 Equinox and of course I EDC the P365. I had a P320 and it was 'okay' but didn't keep it. And I did have a P250 in 45acp that I actually quite liked. I should have hung on to that one.
