You can take the "15 minute trigger job" a step further quite easily. Once you are done with your "15 Minute Trigger Job" do a simple test.
With the Hammer Cocked and the Safety in the On Safe Position pull the trigger taking note of how much movement there is from the trigger being AT REST until it contacts the safety. A simple set screw will eliminate 90% of this pertravel and provide for a much, much better feeling trigger.
Simply remove the grip (and grip screw) and insert a 1/4" x 28 TPI 1/4" long set screw in the grip screw hole in the lower receiver. Screw this set screw in (again with the Hammer Cocked and the Safety in the On Safe Position) in until the tail of the trigger is pushed up against the safety. I have run into a few lower receivers in which the grip screw hole did not have threads tapped all the way through into the inside of the lower receiver. This is a simple job to fix with a 1/4" x 28 TPI thread tap and takes about a minute.
JARD Inc. uses a similar set screw to adjust the engagement of their Adjustable Triggers. You can go to the JARD Inc. web site and download their installation instructions for their trigger to see what I am referring to.
Superior Arms also advertises their lower receivers as having a hole to install a set screw to eliminate pre-travel and adjust trigger / hammer engagement. Truth be known all AR Lower Receivers have this hole drilled and tapped it is just that some are not tapped all the way through to the inside of the lower receivers.
This modification may not be for everyone but for someone wanting a better feeling trigger with minimal cost it may be worth a try. It is also easily reversible if the user does not like the feel, just take the set screw back out.
