A friend has a Uberti 1803 (?) Harpers Ferry flint pistol. The hammer and frizzen springs are too weak to make good sparks. Does anyone still make replacement locks for this gun?
Do they use the same lock as the 1803 Harpers Ferry rifle?
I have a Pedersoli Harper's Ferry made from a kit that sparks just fine. Instead of blaming the lock and the springs, maybe the lock just needs some polishing and "tuning". There's an awful lot of friction going on in there that can inhibit spring action. Pretty typical for an Italian "repro" gun. Maybe all you need to do is to get rid of all that friction and it'll function just fine.
