Loose screws on a S&W 686-6
I finaly have discovered why my 686 has been haveing difficulty setting of primers.
According to a man at Smith and Wesson, every screw on the gun is made to be screwd in as far as it can go. Then, they take an air-wrench and further tighten the screws. The screw on that sets the mainspring is set by fileing the tip of the screw in such a way that it is supposed to be screwd in as far as it could go.
Well, after hand tightening the screw on the main spring, I proceeded to fire ~70 rounds, and at the end of the day the screw on the main spring had managed to come about 2 turns loose. Later, as I was cleaning the gun, the forward screw on the rear sight had almost come competely out. By the way, two calls to S&W were made, the first call they pointed out the main spring screw should simply be fully tightened, after reporting the loosening of the screws they said that at the factory they used an air wrench to tighten the screws and so they were probbably simply not tight enough. . .
So I guess I need to hunt down the appropriate screw-drivers for every screw on the gun (as a lot of 'em have been comeing loose) and possibly even hunt down an air wrench. . . :roll:
However, if the screws had all been tightened down at the factory, using a air-wrench, to a point where they would not come loose, then I doubt even an air-wrench will fix my problem. So, I have a strange feeling I'm going to have to put lock-tight or a similar product on every screw.
Does this sound like a good or bad idea considering the situation with the screws on the gun? I really did expect the quality on this gun to be better. . . It's only had about 1,000 rounds through it.

Clean the screw and the threaded hole, then use Locktite "Blue" or 242 as it's known. It will hold the screw and not let it back out. The 242 will let you take it apart without using heat and cut down on the possibility of breaking it off. The red will need heat and force to remove it.
