I met Casey and Brandon recently and I can tell you that I am even more convinced that my decision to go all SV was the right one. My experience has not been without issues, but instead of the normal "It's your ammo" answer, what I got was, "It is this very particular aspect of your ammo, and here is why that is bad in my gun where it may work in other guns" They explained in detail, with calipers, how they do things differently and why that was the better way to go. I felt like I had received a free education instead of an excuse. Lots of builders can build guns that run, few builders can built guns that suit your particular tastes. I know that you have already bought the SV, (congrats on a good choice) but the best advice that I can give is to buy the one that you will be the happiest to shoot, and shoot the piss out of it.
I am in LA, and I have, among my stable of SV's, a 5.4" limited gun. PM me and I'll meet up with you at a match and you can finger it.
