there have been two automatic revolvers in history that I know of: the Webley-Fosberry (.455 Webley) and Mateba model 6 Unica (.357 Magnum) . does anyone know if they actually work well enough to merit buying one?
I expect the first part of your question could be best answered as they work well considering what they are and why no major firearm company went down that path. Buying one is solely based on the collectible value. I'd like to have one, hard to find and the $$ is more than most will spend.
