Just picked up a used 640 2" ss ,38 special SN BNF9xxx and I am interested in any possible info on gun like year and any other particulars, and maybe any reload ammo sucess in lswc and w231 powder (was sold 105 gr. due to gun size?? and cannot find a load in my manuals they said to start with 4.8 and go up ) or maybe I will just take them back for 125's. Thanks in advance.

Is it a .38special or a .357 magnum gun?

For practice in either mag or special guns I personally stick to 158gr SWC lead bullets.

The 105gr bullets are way to light, IMHO.

1993 according to Standard Catalog of Smith & Wesson (2nd. Edition) by Jim Supica and Richard Nahas. A 3rd. Edition is about to hit the bookshops. Also see: www.armchairgunshow.com

My 640 is of the same vintage. Great gun you will like it. Mine likes the 158 +P SWC's best. I have shot over 2500 rounds through the gun since '93 most being +P's. Still as tight as the day I got it. As far as the reloading goes pick up a good manual, there are plenty of .38 loads existing around the 158 grain SWC.

It should be the .38 Spl version. The 640-1 was the magnum revolver.

Thanks for all the info. I went to the range with gun and came home, cleaned gun normally and the whole cylinder FELL OUT :uhoh: I am fairly new to handguns and own a couple others with no problems like his ever. I put it back and can feel it pop in but when spining the cyl. it is very loose and has allt of play in it and does not take much to pop out.I will be calling the dealer but wanted some ideas before hand . Thanks again.

Which way did it come out? To the side or to the front of the gun?

It came out to the front, just noticed the screw on the side fell out:uhoh: Now I put it back and it seems ok . Why would it do this?? And should I be concerned for future problems?? I will still be contacting dealer to let him know. Thanks

Ya'..... Well...

That screw is what holds the cylinder assembly in place. That way if you need to clean the yoke (the part the cylinder swings out on) or take the cylinder assembly apart, you can do so. When the screw isn't there the cylinder will come off on its own. Smith & Wesson's been making revolvers that way since the late 1890's. The revolver should be checked over by a gunsmith, but I would think that so long as you keep the screw tight you should be good to go.

I had a feeling that was the problem but I didn't want to jump to any conclusions. My uncle, Old Fuff, gave you some good advice.
