Get some "Moly" just lube it with the right lube. I have done this with every gun so far and it has been like an expensive trigger job without the high cost. It can lower the trigger pull by up to 50% right away besides smoothing it out too. A small can of moly costs like $20 its the best buy you will ever make. I do upall my guns with moly i use it on trigger sears, in semi auto pistols on the slides, on the barrel and barrel bushings and hammer faces. I put it anywhere there is metal to metal contact.
Moly reduces all friction, all wear and prevents all galling too. It works into the small pores of the metal and wears against itself there is no metal to metal contact on the moving parts its moly against moly it wears against itself. No matter how much you shoot the gun it will never show any sign of wear at all. Moly can be really messy when not done right. I take my 45 frame and empty slide and i apply moly to the rails and work it in by running it back and forth many times. Then i wipe the excess off and assembly the gun. I leave the barrel and bushing coated. I put it on the trigger sear and take it shooting. Then clean it and apply it again the more it works in the smoother and better the trigger gets just with a lube thats it!! Since moly stays where you put it you can wipe off the excess after you assembly the gun and its good to go. All my guns are moly'ed up they never leave home or get shot without it there isn't a lube on the planet that can even match it. I use it in my semi auto rifles in the gas systems too besides on the bolt and the bolt carriers and the sears also. I use it in my bolt actions too on the bolt lugs and sears also and even where the bolt slides inside the reciever too just a little will remove the friction and prevent wear.
BTW; All my springs are coated with moly also I never let springs run dry. I have seen so many springs left dry and they have to be replaced because of wear. Thats just plain dumb.
