hi folks, real new to the computer world so bear with me, i have a s nw model 1 inside a circle, is it a pre m-10, or some say it's 1905 m 4th change s/n c 422284 can you help
C 422,XXX is listed as 1957-59. If it's a steel frame .38 special and it's not marked "MOD-10" in the yoke cut, it's a post-war .38 M&P (Military & Police). Model numbers were assigned in 1957 and some folks call the post-war non-model marked guns a Pre-Model 10.
