There are good ones and bad ones from all eras of production. The lockwork before the 1950 changes was better for double action shooting, but the post-1950 short-action lockwork is often better for single-action shooting.
The fitting and finish took a down-turn in the late 1960's and early 1970's but improved again in the late 1970's and later.
Some find that the full underlug barrels in 6" and 8 3/8" are too muzzle-heavy and others like them better--is a matter of presonal preference.
Most of them shoot well once you find which ammo they like. I have owned 7 or 8 M-17's and M-18's and only had one that I thought was not particularly accurate. I have had a few of the J-frame .22's and never found them to be as accurate as the K-frames. (including an M-35 target model--but in it's defence it was well used).
