The new model Rugers are the easiest as are the BFR's.
I grind half the hammer sear surface off and polish to remove all creep. Then I break the sharp edge with the ceramic stone.
That takes care of the creep.
All else is done with the trigger spring, never the mainspring. Ruger mainsprings take a set after time so I switched to Wolff over power.
Standard springs are 22 to 23# but once a set takes place, accuracy will fall off and I got tired of changing springs every year of IHMSA shooting.
Folks do not realize how important a mainspring is to accuracy and even though the gun will fire, you lose a great deal.
This is what the proper trigger job and over power mainspring will do at 50 yards. I shot this with a BFR .500 JRH, 440 gr cast and 29.5 gr of 296. It is an over grown Ruger, same internal parts.
