To each his own I guess. I see the handgun as a defensive weapon. And just can't bring myself to drop that much on one handgun. I guess I am more of a rifle guy, and would rather invest that money into a SIG 55X, or another HK.
Still all said and done I'd go with an RRA given the choices. These guys are tight, have learned from the best there is, and have been running their own business for what 8 years now? I was very impressed with what they did on the trigger group in my AR. They also also have the confidence to stick with what they know, which is 1911's and .223 AR's.
