The only revolver I am aware of that can be actually wear a can and be silenced. It's alot of history for the money. It shoots various .32 revolver ammo safely, it's butt ugly and has the worse trigger pull in d/a of any revolver known to man. That's all I can think of now and I am glad I could help.
There was a nice write up on them in the December backwoodsmen. Where did you pick it up and do they have more it would be nice to not have to order one online.
Gander Mountain and KS&E guns have them. As of today both places still had 4-5. They are now $149.00. Small price to pay for a little history! KS&E actually has the ammo in stock too!
Regarding ammo, I think if you see a decent price for the factory stuff (<50 cent/rd), you should buy some even if you don't need it. It seems the supply drys up every once and awhile. Also, just recently there has been some 70's Russian surplus hit the market. The commercial, factory ammo is mild, but the surplus has a decent kick to it (still pleasant to shoot).
