I had been considering the Marlin or Rossi lever action .357 as a sidekick to my handguns, but this 77/357 makes more sense for the shooting that I do. Does Timney or anyone else make an aftermarket trigger for this rifle? How expensive would it be to add that new trigger? I've added new triggers to a couple of my rifles, and as most of us recognize, once you use a great trigger, bad ones are simply unacceptable.
