We have 3 pair, all have  the handsome high quality medallions already installed so make sure to add medallions ($15) when you order these grips.    Very good quality material, machined, sanded and hand polished, not cast or molded, these are very nice. 

If you're not sure if you have a J, K or N frame, just flip out the cylinder and it should be stamped on the inside of the frame. For additional Smith and Wesson model to frame information, see the list picture below.
