I am a new member I want to provide info on a hand gun I purchased a few years ago. It is a model 13-1 ser. No. D931545 .357 Magnum. I have fired a few rounds through it both .38 special as well as .357. It does have a 4" barrel and it fires very well. I have cleaned both the hammer and trigger and it removed the hardening marks. Any information on this would be appreciated. This is a M&P model from what I understand.
