Hi folks, I am rather new to the revolver world, most of my handguns have been autos. I picked up a really nice S&W model 65-2, SS .357 revolver, in a pawn shop. The serial number indicates it was made in 1982. This revolver has a screw adjustment for the mainspring, located near the bottom of the front strap. You can adjust the trigger pull from "blow on it" to two hand trigger pull. Is this a standard feature for this gun? Also, some former owner buggered up some of the action screws that I would like to replace (with the proper screwdriver), and I have not located a source. I tried Numerich and Bob's, with no luck. This gun really kind of hacked me off. The first time I shot it, I shot it better than the 1911 pistol I have carried and shot for years. I believe this revolver has a homing divice of some sort for the bullets. Any help is appreciated.
