Another "exotic" 9mm fan!
I have a Smith airweight J frame model 37 in nickel that I got fitted with a 9mm cylinder. (A Model 937?) Don't shoot it much with that cylinder, and light loads at that. For practice I'll normally stick the .38 cylinder back in. If I wanna do lotsa revo practice I go to the 3" mod. 66 or 4" 625 Mtn Gun. Herr Jaegermeister, good luck on the 9mm Ruger, the 2.75" ones are not common, the 4" are about mythical. There's one that I've seen, at the NRA Museum in Va. Most of the 4 inchers apparently went overseas to fill a contract, and they never made it back here--yet, anyhow, keep your fingers crossed! And when you see any of them on the auction sites, the sellers must think that IDPA folks will go nutz, and price them accordingly. I've seen two of the 2 3/4 " ones list for something like $700-$800. Of course they didn't sell, and I'm not sure I'd try to strike ANY kind of deal with a seller like that!
