Looking for opinions on the lightest recoil 38 special rounds that are factory produced off the shelf ammo. Was wondering if the lighter grain stuff is better than the heavier grain stuff like say 115 grn 9mm kicks less than the 147 grain stuff does. Looking for suggestions and decent opinions from you fellow 38 special shooters. The test specimens are a 340PD, 642 and M&P 340 (soon to be added in the stable). Thanks..
