All .22 Mag grips at NAA will fit ALL .22 Mags. I turned my Dad onto NAA about 6 years ago.... he bought one of each style & a 'bunch' of extra grips!
I have tried them all and use the original smaller grips only in dress slacks, shirt & tie situations, (up front for communion, etc.). In less crowded, (less eyes!), I go for the rubber or wood oversized grips, which really aid in actual target situations. I also bought the Mini-Master with .22LR conversion cylinder, (for a quicker reload). With the folding 'holster' grip, accuracy IS attainable, though it's kind of ugly for show & tell!

Although the holster shown here is very cool.... I NEVER use a holster for any of my NAA's, (since they now make their cylinders with the safety slots, you can carry them fully loaded-see attachment). Every now and again I'll run a Q-tip through the chambers and barrel to eliminate pocket lint. They are safe, (by themselves) in your pocket.... I've been using them for decades. IMHO, everyone should have at least one of NAA's fine revolvers. They eliminate the excuse that you cannot always carry-except where prohibited by law of course!
