I counted. I have an even dozen. I honestly never thought about it before. Truly coincidently, I chose 13-30 as "many" before I counted. I have probably owned as many as 15 or 16 at a time and have owned probably 50 over the years.
I am not a collector. I try to keep it down to "purpose-driven" guns. This one is super concealable, that one is a full size .45 semi for HD, one is a 9mm range gun, another 9mm EDC pocket pistol....
I admit to having a couple of "dupes" in function, just because. An S&W CS45 and a SIG P245, for instance.
I guess "many" is one more than you have a function for. I, then, am marginally "many".
There is no such number as "too many", though, so don't bother with that poll.
But right now I'm not driven to buy another and I plan to keep what I have.
I am kinda thing about getting a new shotgun, though.
