Of course you can. The whole issue over whether or not this or that S&W revolver can use +P only came about when they started introducing models with aluminum frames and cylinders. When they dropped the aluminum cylinders due to very short lifespans, the issue persisted regarding the aluminum framed revolvers, but it has no relation at all to all-steel S&W revolvers, not matter the model, so long as it's not an antique, as gun steels were softer back then.

Now, will a regular diet of +P accelerate wear? Sure. At least some. So don't feed it a regular diet of the stuff if you plan to pass it on to your grandkids.
