I bought a NIB Winchester 52B repro, always wanted a real 52B sported, but never found one I could afford. Anyway the trigger is atrocious on this one, yes it is adjustable, from 5 to 8 lbs, mine is a little worse going from 7 to 10 pounds. Does anyone make a replacement drop in or any suggestions on who I can send this one to ? Thanks for the help.
