Not terribly rare. I had one & foolishly sold it to a son-in-law. I have another friend who has one now, but doesn't really want to sell. Also saw one at Spiritwood, Sask gun-show a couple of weeks ago. Terribly over-priced!
Nice guns, but 32 Long /& 32 Short Colt ammo is hard to find & pricey. 32 RF ammo is almost impossible to find & commands collector prices.
Post a WTB ad in the EE & haunt gun-shows if you really want one. Good Luck.
