I own both, and think both are great, but if I could only have one, I wouldn't trade the Sig for a truck load of HKs if I couldn't replace it. I have put lots of rounds through both of my Sigs, the 229 had two barrels, .357 and .40. Shooting reloads or factory ammo, I have never had a jam or malfunction of any kind that would make me doubt the Sig. I like the HK, but mine doesn't always digest reloads. To me, if you can't trust it, or have doubts, you might as well leave it at home and take a wheel gun.
