Serbu BFG-50A. semi-auto 50BMG. but 3 yr waitlist. Barrett Model 82A1 (29") as a close substitute, but not a fan of the moving barrel. Yeah, I know 50BMG is obsolete for long-distance reach-out-and-touch-someone, surpassed by newer calibers. but still want.
S&W 1006. full-size, 10mm, all steel, hammer-fired, DA/SA, with decocker (personal preference).
H&K P7M8 9mm squeeze-cocker. although out-dated, it's a classic.
S&W 8-3/8" M29, blued, old-school. maybe accept Colt 8" Anaconda as a substitute.
come kind of clone of Colt Single-Action Army, in 45 Long Colt. 7" barrel, maybe 5" barrel. torn on that. I'd want a matching pair. for the western-style holsters, of course.
