Yes, you can but it is NOT recommended. Only shoot +p ammo in .38SPL guns that are marked as +P.
yes, but don't shoot the P ammo too often
The mfg. Says yes you can
As long as the +p is SAAMI approved ammunition
You can, but, you should not. The frame is not rated for +P
No. It's not rated for +P ammo. The 649 is, though.
.357 Magnum and .38 Special (to include +P and +P+ loadings).
Yes it does. The M&P is a fine weapon.
38 Special. Stay away from +P
NO
Not recommended unless the maker says it is OK to do.
Depends on how old the revolver is.
