627 snubbie is eight rounds of 357 magnum goodness, but it is an N frame revolver but surprising carries smaller . I'm not a fan of J frame 357 magnum revolvers. Great for 38 Special but not a lot of fun with full power 357 magnum loads but S&W Model 66 is a good compromise between the size and ability to handle the hotter loads. As a K frame, it fits nicely between the S&W 640 and the 686 in size.
Charter Pulls Pit Bull is an interesting one. Pretty big and around the same size of an N frame snubbie. Action will need work or at least the two I handled did.
