+p and +p+ are 'hotter' rounds. In simple terms +p means its got more powder, and +p+ would mean even more. More powder means a faster round, but it also means alot more pressure on the round. Some firearms are not rated for shooting +p ammo. I would check with Ruger C.S. to assure the blackhawk is safe to shoot +p

Right now its just hard to get any ammo.

If you can find it there's Remington, Fiocchi, UMC, and Federal jacketed soft point that I have used before without any problems (those were regular load not +p)
