Mach, those are some nice pieces, I'm jealous.
There's always been something about the S&W autos that I like in the looks department, and the 3913 I had was a flawless performer.
Stupid question maybe, how long would it take to wear one out on full power (original load) ammo? I don't shoot 1k rounds a week, but I do intend to give it a lot of range time through the course of my lifetime.
