I'm looking at a reproduction blackpowder pistol made by CVA. The guy wants like $50 for it. I brought it home to try it out and with one fall of the hammer, the sear broke. it is the part of the sear that engages the tumbler. I cannot seem to track down anywhere on the internet where I can get a replacement. It also needs a nipple. If anyone has these items or know of where I can get them, it would be greatly appreciated. Thanks!
