TG - have done a lot of these "trigger jobs", however .... I want a full mil-spec hammer spring ( as LR stated ) for max primer strike. You won't feel the difference on the trigger. I use a very fine stone to polish the seer surfaces and then some teflon oil on 'em. I got a 1/4" tap and run out the threaded hole that the grip mounts in and run a 1/4" long set screw up the channel before mounting the grip (and it gets a spot of loctite ). I also drill and tap a hole up between the lugs for the retaining pin and put another set screw with a soft tip up that way to take "most" of the play out between the upper and the lower. This hole comes out at the top end of the ramped grip mounting gussett. Then, I bob the hammer to reduce the orbital mass for improved lock time.
Doing this, I take out almost all of the creep and overtravel. Keeping the original mil-spec springs insures a solid primer strike an, since there is so little trigger travel, keeping the original trigger spring is almost not discernable.
You can get the set screws from Home Depot but I order 'em thru McMaster in Chicago - a lot cheaper and true MS quality. Overnight delivery as well.
