I've only got one and I can identify somewhere between 8 and 15 specific guns or specific types of gun (with exact model undetermined), that I'd like to have for various purposes (including one that is essentially useless but which I'd like to have just because).
The one that I have is my .22 plinking pistol, a Ruger Mark III Hunter.
The others, in no particular order, are:
A centerfire range pistol, I want a Taurus PT99
A .22 rifle
A centerfire rifle, possibly an AR-15
A 20 gauge shotgun
A primary carry gun -- to be a Taurus 85 revolver
One of those beautiful, little, small caliber "lady's guns" of a size that would fit in the tiniest evening bag just because I want one.
A single-action .22 revolver because I believe that's the best gun to teach children and newbies the fundamentals, probably a Bearcat because I have two young sons who will grow into it.
Some kind of handgun chambered in .45 in case I ever need to make larger holes for whatever reason.
A blackpowder pistol for Civil War reenacting?
2-3 extras of my favorite types in case one is in need of repair or to have on hand when taking people who don't have guns shooting.
