Most 1911s, except for the really short slide lengths, all of the Sigs, CZs with the manual safeties, S&W "L" and "N" frame revolvers (my Model 27, the older 627s, and the 625), royal-blue Colt Pythons with the older-style wood target grips, the Glock 17, and the HK USP compact .40 or .45 or the P2000 LEM trigger in 9mm or .40.
