Justus1213 the main thing to remember about the ammo is too stay away from the 110 - 125 gr. Magnum loads. I have read several articles about how those can cause damage to the forcing cones. The .38 Special ammo is not powerful enough to cause damage to the forcing cones. Does that mean you can not use the 110 - 125 gr. Magnums in it? No, but do so sparingly. It seems the constant use of them is detrimental. At home all my K-frames currently have .38 Special +P ammo and my L and N frame S&W and Colt have the 125 Gr. SJHP Magnum load. They use different speed loaders so getting them mixed up is not much of a problem.
