Ruger Single Six Convertible??

I have a Ruger Single Six that I purchased used a number of years ago and I received a 22 WMR cylinder with it. However, since it was used, I don't have the box the gun came in or any documentation with it and I don't believe I've ever used the Mag cylinder. I can't even remember for sure where i bought it....maybe from a dealer at a gun show. So, I'm getting interested in shooting some 22 Mags with it and I can't be absolutely sure the extra mag cylinder came from the factory with this gun. I don't see any markings on the cylinder that identify it as a Mag cylinder (someone wrote 22 mag on the cylinder box in ink) and also I see no markings on the gun that it was made as a convertible at the factory.

I read somewhere that if the cylinder fit in and locked up it was safe to shoot. What say you??? I would especially appreciate anyone with a firsthand knowledge of this situation (Ruger Single Six and 22 Mag cylinders, etc) to give me your advice. I don't want to take the time or incur the expense of sending this back to the factory unless there's no other way to check it out.

I will note that the marking on the left side of the gun says, "Ruger .22 CAL. SINGLE SIX" and not .22 LR like so many 22 caliber guns do.

Thanks for the info!

I checked the serial number online, looking under the old model "magnum" series on Ruger's website and the serial number appeared to fit in the 1968/1969 time frame.

Also, I checked both cylinders and, after a little cleaning, I found the last three numbers of the gun's serial number engraved on both cylinders on the end. So I feel comfortable that the gun was produced as a convertible and that I have the two cylinders that came with it from the factory. Guess I'll go buy some 22 MAG ammo and have a go at it!!

Thanks, guys!

Thanks again!

Thanks again, guys, for all the input! I do plan to shoot this gun with both cylinders.....should have shot the 22Mag side long ago, just never got around to it. But I have shot it with 22 LR some over the years.

After finding the serial nos etched into the cylnders, I also called Ruger and got the info they could tell me about the gun from the serial number. It was shipped in December, 1968, it has a 5 1/2 inch barrel and was shipped with 2 cylinders. The model no she gave me was RS5X...not sure what all of that meant, but she did say the X meant it was a convertible gun.
Interesting what all you can learn when you start digging into things a little bit!

I'm planning on attending a local gun show tomorrow and hope to pick up one or two boxes of 22 MAG ammo and maybe a box of 22LR stingers. I'd sort of like to find a decent 22 MAG rifle also. We have some Yotes around here that I'd like to thin out. If I do shoot at them, it will be at a short distance...probably no more than 50 yards. We live on 10 acres, but there are houses in all directions. My property is long and narrow and I think I might be able to call them in down back around a creek bottom and get a shot, esp if I can get up in a tree stand and use an electronic caller/decoy to get them in and keep them distracted!! Could safely shoot down into the area around the creek....
