Hello from a stone's throw from Philly.
I've been LTCF'ing in PA since '85, back when permits were like hens' teeth. These days I shoot mostly SIGs, and I take perverse pride in getting others to make the jump to them from other manufacturers, and that hideous 1911 platform. "Dances with fuglies" :hand5: knows exactly what I mean!
Oh, and yeah, 9 is enough, but .357 SIG tends to leave them that much flatter, that much sooner. "Real" calibers don't have to begin with a 4!
