Not recommended
No. This was made long before +P ammo was created.
1. It can, but, it is not advised. 2. It is stated by Smith and Wesson that the model 14-3, which is the third change of the model 14 can safely shoot plus P ammunition.

Mid 80's. Call S&W and they will tell you when it left the factory. Standard Catalog of Smith and Wesson, 3rd edition.
Only if the owner's manual says so.
Steady use is not recommended
1. Yes. I obtained this information by emailing Smith & Wesson directly. 2. The model 15 is a K frame .38 special revolver. The 3 suffix means third change. All K frame models from the first change onwards are rated for plus P ammunition. As are N frame revolvers and L frame. The plus P ammunition does reduce average service life as you might expect.
New $650.00 plus (uncle Sam) Tax.
