I just bought a M 60 PRO 357 with the 3 inch barrel. I went to the range today and it shoots great. It will be used as a CC gun along with my M&P 357 Sig compact. This my first J frame I have a 4 inch 686 and a 6 inch Dan Wesson and shoot med. to heavy loads in them and I know they will not be hurt by those loads and they are fun to shoot in them. I tried two of the Med. loads (15.5 grs. of 2400 behind a 125 gr. JHP) That was all of that load I wanted to shoot in the J frame I had loaded some light loads (14 gr of 2400, 125 gr JHP) and they shot great and did not hurt the back of my trigger finger. Will a steady diet of this load hurt this gun as I would like to use it as an ever day load. Thanks for any info on J frames.

As long as your load does not exceed SAAMI specifications for the 357 Magnum Cartridge,
the Model 60 will handle them.
