I own several "factory" rifles and guns, though not all are Pedersoli.
The lock on my Pedersoli Frontier, bought as a
Cabela's Blue Ridge Hunter was very good back in 1994 when it was purchased. It was a large lock compared to Pedersoli's other flintlock rifles, and I wouldn't mind having one again in .54. (As a gift or wait until it goes on sale). Mine at the time was in .50, and I sold it to a young man getting into flintlock hunting. :grin:
The barrel on the Frontier is shorter (39") than that on the Pedersoli Pennsylvania rifle, but the Pennsylvania has a smaller lock, and the largest caliber offered is a .45. Other than those two, their Jaeger gets good reviews as a flinter, and that's the only short barrel version of their flinters that I like...just personal preference. I prefer my rifles with barrels 38" or longer for big game calibers, in most cases.
My Blue Ridge Hunter's lock sparked well, and was pretty reliable in that respect. Pedersoli in that model uses a "patent breech" so you have to be sure to clean breech area in a special manner. The Pedersoli locks are priced about $100 higher from parts supplies than better made Chambers or Davis locks. I don't know why unless it's the currency exchange rate.
I have a Pedersoli trade gun and the frizzen was poorly heat treated, and the ramrod thimbles were very badly installed. :idunno: I think the lock quality on the Bess muskets has declined over the years, but you're asking about rifles, not muskets nor trade guns, eh?
I hope this helps.
