The HKs are nice pistols, I owned a USP compact. The gun was nice but it just didnt feel that great for Carry as well as long range sesions for me.
The slide of the USP used to dig into my skin due to all the sharp adges on the slide. The Sig has a nice rounded slide, very friendly to the skin. And for me the grip is just unbeatable, I have yet to find another pistol that feels as good in my hands.
Carrying cocked and locked has never been a big deal to me. I carry Glocks and Sigs with one in the tube and feel very comfortable doing so. But if C&L carry is a big deal to you than I guess the HK would be the only way to go.
Well, I sold my USP for a second P239 and some goodies. What made the decition for me is the fact that HKs customer service sucks big time, atleast in my experience. When I called Sig up for a new trigger spring, I started to tell them I was going to use a master card. They said dont worry about it just give me your address. It wasnt even a week and a package was at my door with 5 trigger springs and a package of stainless grip screws for the heck of it.
It was a small gesture bu tit sold me on Sig, they are a great company all around the board. Needless to say, my stock blued P220 is my pride and joy. If I want to look good at the range I just break her out and thats that.
Looks nice with Kingwood grips also, thats something you cant do with the HK
Both great guns though, Sig is just my preference.
Good luck!
