Not an easy trigger swap because the trigger mechanism and guard are all one piece, thank you T/C for another great innovation. You have to work on the lock, specifically the depth of engagement of the sear to the full cock notch of the tumbler. It's a "cut and try" job which involves several times disassembling the lock, stoning the full cock notch and reassembling the lock. It is easily within the capability of any careful "gun tinkerer" to get a nice, crisp 3 pound pull. Of course any gunsmith can do it but I have no idea what they would charge, I'd charge twenty bucks but I don't have to make a living as a gunsmith. The modern gunsmith needs a very substantial investment in machinery and tools and is constantly buying more tools for special applications, all of which must be paid for somehow. Back in the muzzleloading era there were itinerant gunsmiths who traveled around the backwoods countryside with just a bag of tools on a mule and that was all they needed to fix about anything. That's why I only work on muzzleloaders myself, they don't require a fully equipped machine shop.
