I'd agree with the HK. I carry a USP .45 Compact as my very favorite gun. Variant one, I carry with a round in the chamber, hammer down. I certainly wouldn't argue with those who said any of the Sig family, especially the 220.
Of course this stems from my own personal choice with design selection. I don't like a single action only like the 1911s. I will tolerate the DAO type (I own Glocks, an XD, and will likely get a Smith M&P) but I don't regard them as "best out of the box" because to get that distinction, to me, it must be da/sa capable. I like the safety of condition two carry but the trigger control of single action fire. As much as I like my Glock (I'm still getting to know my XD, don't have enough personal experience to form an opinion) I hate their triggers. Even my model 34 wasn't up to the standards of my USP.
