Older S&Ws won't have the +P on the barrel. This question comes up a LOT. It's smarter just to stamp it rather have people in doubt for 40 years. (+P has been around since around the mid 70's)
Smith says that any ALL STEEL gun with a model number can shoot +P ammo. This MAY NOT MEAN that it should be fired all the time with +P because it will increase the rate of wear. In other words, instead of a J frame Smith lasting for about 30,000 rounds, you will only get around 28,000 if you shoot continuous +P loads.,
Now some guns, like small and light, ALLOY framed guns will shake loose quicker with a steady diet of +P rounds. Which I can relate to because continuous +P through an alloy j frame gun makes ME shake loose a lot faster.
