If you mean +P ammo the answer is no. It is rated for standard pressure ammo only.
If you mean can you fire non plus P ammo in a gun rated for plus P, yes, you can safely do that as long as it is the correct caliber.
It means (X)treme (T)erminal (P)enetration
yes, but better to use standard ammo. +P ammo shakes the pistol a lot.
Pressure
I don't think there is any +P ammo made for the 32 auto ????????
yes, but don't shoot the P ammo too often
Should be good. Check to make sure the ammo is NOT marked +P. Your pistol is not rated for +P ammo.
no
Yes.
With civiian ammo, it is the caliber. Military ammo- year made, and where
I wouldn't use +P ammo if the barrel is not specifically marked for it. Especially in an S&W airlite. I would not be apprehensive about using +P ammo in a Ruger Service Six, however, since it is much more robust. Even tho it is not marked +P on the barrel. +P did not exist when those Rugers were made, at least not mine.
