There are many weapons I would never buy. Some because i don't like them, others for no paticular reason. For example surplus handguns like Webley or Nagant revolvers, TT33 or CZ52 pistols, stuff like that... Surplus SMGs, wood-stocked bolt-actions, shotguns without shoulder stock, shotguns that are NOT a 12 gauge, Springfield XD, Desert Eagle, single shot pistols and rifles, pump-action rifles, double-barrel shotguns, Drilling rifles, .40 caliber pistols, longer than 5" barrel handguns, revolvers in bigger than .44 mag /.45 colt caliber, rifles in wildcat caliber, AK type rifles in .308 and Romanian PSLs, .22 target pistols with these uber ergonomic wood grips, military carbines in calibers other than 5.56, 7.62x 39/51 and 5.45x39, ARs shorter than 10.5" or longer than 20", S&W Sigma, Winchester Super X2, Colt 2000, revolvers other than S&W and Ruger, pistols smaller than Glock 26, engraved, gold or pearl handled weapons, ect. I bet there's some more stuff I wouldn't buy, but this is what I can think of off the top of my head
