I have a colt new frontier .22cal revolver that I recently purchased. My father also has a new frontier and his came with a .22mag cylinder. My question is, can I use his mag cylinder in my new frontier? Why or why not? I would never attemp this for the sole purpose of safety unless I am 100% positive that it is acceptable.
Heed the man that owns but one gun, he likely knows how to use it
I'm not certain there is a difference in the metallurgy of the two frames, one for just 22 LR and one for the 22 Mag.(I doubt it) HOWEVER...You would be extremely lucky if the Mag cylinder properly fit your frame as is as it wasn't fit to your frame at the factory. Even if it did fit into your frame there may well be issues with timing as well as overall "slop" which could make the thing a bit dangerous. Me...I wouldn't do it without a "good" gunsmith looking things over as far a dimensions and fit. And once he did, I doubt he'd give you the go ahead because of the measurements and fit. JMHO
Generally speaking, cylinders have to be timed to the gun frame they are installed in. If not, the hole in the cylinder doesn't match up with the bore which could be bothersom or it could be dangerous depending how far off time it is.
