Taurus pistols were designed to use cartridges loaded to the limits shown
below. Other cartridges of various types or bullet weights may or may not
function acceptably; such ammunition should be thoroughly tested by the
user before relying on it. Because of the widely differing specifications of
such other ammunition, Taurus cannot be responsibie for malfunctions
resulting from its use.
For .45acp, they say max 230Gr FMJ @ 835 fps.

“Plus-P’, “Plus-P-Plus” or other ultra or high velocity 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 pistols and could therefore be
You need to check out the ammo and see if it falls within the design parameters for the pistol.
I have found that my PT145 likes to digest the 185 gr better than the 230 gr weights. The Taurus ammo is obviously designed to work best with there .45 acp pistols. Plus with the lighter bullet there is be some reduction in recoil which will get you back on target quicker... and remember... the 185 gr may not mushroom, but hey, it will never shrink.
