I have done over a hundred in the past thirty years and what I do makes a completely new trigger out of them. They are not necessarily a shotgun trigger at all. Remington designed this trigger group to fit many guns in their lineup. When I am done with a unit it has a set screw installed from the rear of the guard to stop overtravel, about 75% of the trigger movement is eliminated, the trigger is shimmed to eliminate any wobble, the engagement surfaces are stoned to give a smooth non gritty pull and the weight is set to your number. I wont take one down to less than three pounds for a safety issue. It completely changes the who charactor of the trigger and finishes what shoud have been a great trigger to begin with.
