Just like firing 38 Special +P in S&W 38 Special revolvers that pre-date the model number system, it will not blow up your revolver, but it will accelerate wear and tear. I would approach it the same way as with 38 Special revolvers, practice with standard pressure ammo, finish practice with one cylinder full of +P for sight-in and familiarization.

With modern bullets like Federal's HST, Speer's Gold Dot, Remington's Golden Saber, and Winchester's Ranger T, the extra velocity of +P ammo is not required for adequate and reliable expansion. With modern bullets, +P often causes faster expansion, but at the expense of reduced penetration.
