You are watching: High standard double nine convertible cylinder change


I have a High Standard Double 9 .22 pistol.I was reading someplace that this pistol was also available with a .22 magnum cylinder, is that true? If it is, where would I be able to pick up ns .22 magnum cylinder?
The Double Nine (a Sentinel in western dress) was never offered with dual cylinders, in fact, I have no memory of High Standard ever offering ns .22 mag chambering in the Dbl 9 or Sentinel. I don"t believe the higher pressures were compatible with the aluminum frames. My brother still has my sentinel. I will research further and report back if I find anything different.
I see it now. The W-106 was the one with 2 cylinders.. Mine is a W-104

Even if you found a cylinder and made it work (timed etc), you wouldn"t want to use it. Convertible pistols w/.22 Mag cylinders are bored for the larger diameter .22 mag bullet. If it didn"t blow up from increased pressures, you would have dramatically increased bore wear.

On the High Standard Double 9 if under the writtien of Double-Nine say Convertible you would have a Mag cylinder. I know that is because My Dad had got one at the time brand new and it came with the Mag cylinder. My brother has it now and I am looking at it now. Just to clear some that was ask.
If the Double Nine is any thing like my Sentinel Deluxe it appears to be somewhat of a project to change cylinders. The crane pin is deeply set into the frame and the cylinder doesn"t slide off the crane since rearward movement is stopped by the frame. I"ve had several Hi Standard double action revolvers and none of mine had the the Mag cylinder.

my son-in-law has a High Double NIne with a STEEL frame and 2 cylinders one for .22LR and one for .22Mag. They do exist but I have only seen this one example. there were other options too, ie a Durango with a octagon bbl maybe 7" or so long with walnut grips instead of white plastic. some of the early ones even had fluted cylinders. I have one in .22LR & the white plastic grips & smooth cylinder but found some walnut grips years ago at a gun store in Waterloo, IA when on vacation there in the 60"s.

Just to continue with this thread from quote above of my own post........I now OWN a High Standard Double Nine CONVERTIBLE .22LR/.22Mag.

I am really pleased to have found such a nice clean, specimen of the convertible Double Nine. Just found it this wknd at a gun show in WI. It is only the 2nd one I have ever seen and in really nice shape with good bluing yet ie: very, very Little sign of holster wear and very little cylinder wear and it has OK wood grips But they are a bit wider/larger then my older Double Nine grips. The action is very tite and I doubt it was ever fired much and the cylinders show a very light "turn ring".Also my 1963 version has a hammer mounted firing "pin" while the "newer" convertible has the safety transfer bar frame mounted firing pin. It also has a STEEL frame and both cylinders. It"s very easy to change the cylinders: there is a push pin/spring where the crane is attached to the frame, push the tapered pin DOWN with a rod and while holding spring tensioned pin down slide the crane ring out of the frame, you will actually be allowing the rod you are using to push the pin down to come up ie let the crane ring slide under it as you pull the crane ring out. Whola.....cylinder is out and you can then put in the Magnum cylinder in the reverse order. There is the difference of the diameter of the .22LR and the .22Mag but I don"t know just what it is. However, the Ruger Single-Six has been dealing with it for years with no major issues. It may be a problem IF you were to try to bore out a .22LR cylinder and shoot the magnums in that gun BUT if it were a alloy/aluminum frame it may not be so good an idea to try that.
