As to the Ruger, unlike the Single Six 22, which you could swap out a 22-Mag cylinder for a 22-LR cylinder, the "new" Single 9 22-Mag and the "new" Single 10 22-LR do not have the same interchangeability. I have the Single Six with both cylinder's and really like it. I would like it 4 times incrementally more. But…..alas…..
