Personally, I would not put a 'target' trigger in a 'tactical' firearm. Don't get me wrong, the Timney trigger is a very good unit, but it is more suited to a varmit or target firearm. I would go with a stock trigger system then send it trigger parts to Bill Springfield for his 4 lb trigger pull. He smoothes and sweetens the trigger where it is a very nice break but at a tacital weight. Mine is 4 1/4 lbs and feels like it doesn't move at all until it breaks. Of course you could tune the Timney for a heavier pull, but why invest $200 for that when you can get it for $40! 44 Man
