I'm considering a BP pistol as a new "toy" or target pistol (not for hunting or primary self-defense). I would think a single shot would be safer & less expensive & less complicated than a revolver. Does anyone have any suggestions as to what to look for in a first BP pistol? If i don't like it, i'll probably just give it to a nephew, so it needs to be relatively safe (bad pun). Brands? Bad signs? Bad idea overall? Probable price range on single shot in decent/safe used condition (not into cosmetology)? I plan to do a bit of shopping at an upcoming gun show, mostly looking.
