340PD Cylinder Errosion?
My 340PD does not have any errosion and I'd like to keep it that way. S&W said the warning on the barrel, "No Less Than 120 Grain", referrs to .357 only. The CS Rep said it is okay to use lighter .38 ammo. That said what should I use to clean after shooting to ensure the gun is clean, but that the cylinder is not damaged?
