I saw a Cimarron 45 cal. black powder revolver with a .45 [unmentionable (.45 LC)] interchangeable cylinder. Very interesting handgun. Has anyone had any experience with this gun? It really got my attention and interest. The best of both worlds. .45 cal cap and ball and a pretty decent centerfire, all in one frame. I have to admit, it is a bit tricky changing cylinders. Didn't buy it. Yet.
