This was my first modification to my 91A1, feels sweet to me, tell me what you guys think. a nice 3.5 lbs. to release the hammer, appx 1/16" to take up slack, another 1/16" (or less) creep & about the same in over travel. (I know I'll get lectured for such a light pull) the pull out of the box was almost 7lbs. plus had the barrel throated & polished. OK let me have it
