I recently purchased the Model 342pd J frame for my personal carry. I love it and now shooting 38 caliber ammo. My question is: Why does S&W put the following on the barrel of this gun, "No less than 120 gr bullet". I am 81 years old and recoil sensitive. I would like to shoot some 95gr ammo and I am afraid to try it because I don't know what to expect. Any idea's. Should I or shouldn't I? Thanks.
