buying more guns
Might be fun to set some "parameters" then collect as budget (wife?) permits, e.g. "collection limited to 22lr rimfire, 3 revolver calibers (38/357, 44m, 45lc), 3 pistol (9m, 40sw, 45acp) and these quality names of SW, Ruger, Browning, Beretta, Colt, Sig and HK". You could go further to some classic specific models, eg., Browning HP, SW 27, Ruger Redhawk/Blackhawk, Colt SAA, Sig 226, etc.
