I have a older (probably made around1968 going by the serial #) mfg S&W Mod 37 no dash..Is thing rated for +p ammo, or should I just stick with standard velocity .38? Mainly it sits in the nightstand, I 've not shot it much since I bought it, (back in the early 90's) was just wondering if it could handle them, in case I'd need to use it..After watching the snub interview, I'm kinda wanting one to carry in a coat pocket in the fall/winter months, in addition to my EDC.. I'm thinking I want a hammerless snub anyway, so this one will probably continue to live in the nightstand along with the P7..
