Looks like a brass-framed replica of an 1849 Colt.
I’m not trying to be critical, but I don’t think the brass frame is historically “correct.” Doesn’t mean it can’t be fun, though!
No personal experience with this model, but I’ve read that the loading levers are a little prone to bending(?). Take it easy seating the balls, and be sure to use soft/pure lead, for easiest seating.
You can also buy an inexpensive press to load the cylinder off the gun. Might be a good idea, if you plan to shoot it a lot.
I know it’s “just a .31,” but keep the loads light. The brass frames have reputation as being prone to getting “loose” with extensive use- especially with heavy loads.
Hopefully someone with personal experience will chime in!
