Hello again. I recently picked up a 4" nickel S&W M&P .38 sp. The serial number is 450xxx. From searching various forums, I'd place it in the early 20s, correct? It's in pretty good shape and I can't wait to shoot it. I read that it's best to not shoot jacketed ammo, so I got some PMC lead round noses. Is a 158gr LRN at 820 fps OK to put through the gun? I wan't to put the gun under as little stress as possible while still shooting it.
