Jpuke, have you considered contacting Volquertson on the problem? My local libraries have books on gunsmithing, you could check your library establishment. The internet may have something too, use Ruger 10/22, .22 rimfire, gunsmith, etc. as keywords, get some coffee and surf. Let us know how it worked out as I too am looking at the same setup you have, down the road, I really like a good trigger pull :grin: .
Concerning mechanical safeties on firearms...I learned with black powder, let the hammer rest on the loaded nipple while carrying, simply don't point the muzzle at people or things you don't intend to shoot, don't bump the gun, keeps the dings down that way! The French and Russian armies issued guns that did not have safeties (Tokarev pistol, MAS 36 rifle, etc.)
I had a guy at a local gun club in the mid-1990's with a Savage shotgun that would apply the safety all the time, then release when he came to the trap/skeet line for some clays. The safety wore out and the shotgun discharged into the ground near my feet! :x Because he used common sense and pointed it in a safe direction I did not get shot. Remington has been involved in a law suit where a guy released the safety on his M 700 and blew his foot completely off.
I do use the safety when climbing a fence or tree log while hunting. Otherwise I never the a safety device, just use common sense and point the gun away from people, etc.
