Let's see. My menagerie of handguns consists of S&W, Colt, Ruger, Erfurt (P08), Walter, Ithaca (1911A-1), Star, GSG, Taurus, Webley, KelTec, Glock, RIA, H&R and a Soviet Nagant. S&W makes up 60% of the total, with Colt and Ruger each accounting for 10% each. Over 75% of the revolvers are S&W. 1911 type pistols account for almost 60% of the pistols.
The long guns are made up of Inland, Postal Meter, Saginaw SG, Eddystone, Enfield, ROF Fazerkerly, Smith Corona, Springfield Armory (the original one), Ruger, Windom, Remington, Winchester, Marlin and Henry.
At various times I've also had Auto Ord, Llama, Rossi, Cimarron, Sig, ROF Lithgow, Mossberg, Bushmaster, Springfield Armory (the current one), Iver Johnson, and probably a few more I'm unable to recall at the moment.
