New (to me) 640-1

[Trojansteel]

Well, just picked up my first gun, and it's the J frame below. It's a 640-1. I think it's a 1995, since it's pre MIM. Put about 50 rounds through it over the weekend and it worked excellently. One question, when the cylinder is open, there is about a millimeter of back and forth play. When locked up, it's solid. Is a little play normal when opened?

A little front-back play with the cylinder open is normal. That's a slick 640!

That's a nice one! Were you shooting .357's? I have the same frame in M60-9 and it has about 1/16" of travel with the cylinder open. Enjoy! PEN

Thanks Pen [emoji106] I stuck to 38 specials. Will give .357s a try next time at the range.

Nice piece! That is my primary carry gun only difference being mine was Magna-Ported.

110gr .357 loads do well in a steel frame J-magnum like the 640. My Model 60 LadySmith loves them because they kick less than the 125gr and 158gr magnum loads. The 158gr CCI Blazer .357 "medium" load is also a good option in your gun. Enjoy!

I've noticed burrs on the cylinder stop notches. What causes this? Is it a problem? And can I fix it?

The timing of your cylinder rotation to a stopped position is off slightly. Have it corrected by a competent S&W pistolsmith. Only then have the cylinder de-burred at those raised places. ...........
