Ruger’s Incredible Single Six Convertible Revolver

Ruger’s Single Six Convertible revolver comes with two interchangeable cylinders so you can shoot either .22 Long Rifle or .22 WMR cartridges in it. It’s also my single most favorite plinking revolver–specifically the “Super” variant because it has adjustable sights.

The original Single Six Convertible was made from 1962 to 1972 and is found with 4 5/8, 5 1/2, 6 1/2 or 9 1/2-inch barrels. The 4 5/8 inch one is very rare, and the 9 1/2 inch one is just ungainly.

The Super Single Six was made from 1964 to 1972 and came only with either 5 1/2 or 6 1/2-inch barrels.

Some of you may know that the .22 Long Rifle and .22 WMR are actually two different bullet diameters even though they’re both .22s. The .22 Long Rifle is a “heeled” bullet, meaning it has an undersize shank seated into the case and the exposed part of the bullet is the same diameter as the outside of the case–.223-inch. The .22 WMR, on the other hand, uses a conventional jacketed bullet that’s .224-inch.

While it’s perfectly safe to fire the .22 Long Rifle’s smaller bullet down the larger .224-inch bore, the reverse is not necessarily true. That being the case, and to prevent any possible in-factory mix up with undersize bores, all Ruger .22 revolvers have .224-inch bores regardless of whether they’re convertibles or not.

    Timely story for me as I was looking at this very revolver earlier today (maybe late last night). I’m more a pistol than revolver guy. But I do enjoy ruger products.

    • I think a good buddy of mine had one when I was a kid. We plinked the hell out of that thing. I wonder if he still has it? He’s at The Pentagon these days, so I don’t know if he took his guns with him.

    Still have mine from 1983 or so. It is the 6 1/2 barrel. Never heard of Super, but it does have adjustable sights. I use this to introduce new shooters to the sport since it is so sweet to shoot. Still have some 22WMR CCI shotshell rounds for snakes and such.

    This may very well have been the very first handgun that I ever fired in my life! It belonged to the father of a childhood friend, and he took us out shooting and fishing one afternoon. I could not hit jack, but it did not matter… I was hooked for life already!


    • It’s not my first, but probably in the first 3-5 handguns for me as well.

    They ae sweet. I bought mine used but not abused and it shoots lights out. Glad I found mine at a great price. I shoot a lot more LR’s than WMR’s because the WMR’s are still so hard to find with any regularity. Midway has them pretty often but they are gone in minutes every time they get in stock. I have a few but they are saved for serious work not just to plink with. I have plenty of LR’s for those occasions.
