I've handled a couple and think they would be great for reenactments. Cowboy-action shooting...I dunno. I'm not a CAS guy though, so maybe my opinion doesn't count for much on that score. They seem like a great gun for somebody who wants a real western piece that ain't a Winchester and that you no longer see every day. Kinda like a Merwin in pistols. The Colt Lightening (rifle) repros are the same way, as are the Burgess guns. Trouble is the Lightening came in pretty late and the Burgess wasn't very prolific.
When guns are outlawed only outlaws will have guns.
