From the Taurus manual as above, but with more context, as Taurus themselves makes a distinction between +P rated and not +P rated models:
Only fire SAAMI rated Plus P (“+P”) ammunition in Taurus® models designated by Taurus for +P use as
below. Firing +P ammunition in other Taurus products may be dangerous and can result in serious
bodily injury or death.
Model 85 small-frame revolver in 38 Special.
Model 856 revolvers in 38 Special.
Model 850 small-frame revolver in 38 Special.
Model 851 small-frame revolver in 38 Special.
Model 85 Polymer small-frame revolver in 38 Special.
Model 82 medium-frame revolver in 38 Special.
Model 817 compact frame (tracker) revolver in 38 Special.
All firearms chambered in 38 Super Automatic.
All firearms chambered in 45 Automatic (ACP).
All firearms chambered in 9mm Luger.
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.
For Armscor/.RI, I can find only this from their FAQ page:
CAN ARMSCOR GUNS HANDLE +P AMMO?
Yes all of our guns are +p ammo ready, but please use only when necessary.
So this says they are also rated for +P just not quite as verbosely as Taurus does. But even so, I would not turn one of these revolvers away, as they are well regarded by those who have them.
