That would be this revolver:
The Smith & Wesson X-Frame in .460 S&W will chamber and fire the following FIVE different cartridges:
(from left):
.460 S&W
.454 Casull
.45 Colt
AND, if you get the TK Custom moonclip conversion on the .460 through Pinnacle Guns (I like moonclips), you can also chamber
45 ACP
(pic is .45 Colt at left, .45 ACP at right)
AND, if, like me, you have six of the .45 LC chamber inserts for the cowboy-action crowd sitting in a drawer — the inserts that themselves are each a little bitty .22 LR chamber — you can also chamber and fire
.22 LR
(okay, I know a chamber insert is cheating, but…. pic is .22 LR at left, then .45 ACP and .45 Colt)
Fun, fun fun. And the 5″ X-frame is the first X-frame I’ve seen that didn’t look ridiculous.
Let’s see, with a 12-ga shogun, I can fire projectiles ranging from “dust” shot to a .69 caliber
And if you get chamber inserts for your shotgun, you can fire all sorts of cartridges, too (albeit with mediocre accuracy).
Excuse that first comment. I was thumbing away on my PDA while mostly asleep, and I sent it before I had editied it or finished it.
What I was going to say was that most large-caliber revolvers can go this route as well. My Colt Anaconda will fire a lot of different projectiles, and a .44 Mag shot load is fairly impressive. There are mixed defense loads for .44 shot that are bar-sweepers just like a shotgun.
The revolver is much more versatile than the pistol, if concealability is not an issue. Some of the large new 8-shot .357 revolvers may actually be the best of both worlds.
To me, anything larger than .44 magnum in a revolver is a waste, but then I used to say that about .357 and now I own a .44……
This is particularly interesting for folks like me who don’t reload. The ability to have vastly different power levels just by buying a slightly different cartridge is pretty useful.
