There are only four calibers that can carry a “+P” rating from SAAMI. They are 38 Special +P, 9mm Luger +P, 38 Super Automatic and 45 Automatic +P. There is not any other SAAMI approved “+P” loads. Any ammunition in any other caliber marked “+P” is not SAAMI compliant, may be dangerous and should not be used.
Even if your Taurus® firearm is rated for Plus-P (“+P”) ammunition, such ammunition generates pressures significantly in excess of the pressures associated with standard ammunition. Such pressures may affect the useful life of the firearm or exceed the margin of safety built into many firearms. Unless you need +P ammunition, do not use it, particularly for practice.
