Was out shooting my wife's lady the other day. We were shooting mag tech 38's. Noticed the firing pin marks on the brass seemed almost not enough to set the cartridge off. Any ideas? Also when I spin the cylinder the rims of the shells contact the frame when open.

Have you checked for someone having substituted a lightened mainspring?

First thing I would do is check under and behind the ejector star and make sure there is no grit or gunk under there. Mainspring may be a possibility too.

First check that the mainspring has not been cut. More simply, just replace it with a new factory spring.

There is no reason to spin the cylinder while it is open unless you are trying to duplicate what you have seen in the movies. And, cartridge rims striking the frame lug under this situation is completely normal in most S&W revolvers, depending on caliber.

Anything that slows down the trigger affects the strike, like a tired or weakened spring, more likely though will be gunk inside the frame. There are two holes in the breech face and they will collect gunk. My revolver hasn't collected that much....yet.

You didn’t say whether the rounds with the “light strike” went off(?). If they did, don’t worry about it. The only light strike that is significant is the one that causes a misfire.

The suggestion to clean under the ejector star was a good one. An old toothbrush and some cleaning solvent should do it. 38 Spl target loads are somewhat prone to be “dirty” and leave behind fouling.
