Talked with Taurus in Miami today and the representative said definitly no +P or +P+ for PT145's It will Void warranty and could damage frame or recoil spring. Also they rated the Taurus Bullet 185gr Copper Jacket with a 5inch barrel. So 995 fps and 404ft lbs in a 5in would equate to 908fps and 338ft lbs in a 3.25 Inch PT145 . In the PT 145 manual the recommended bullet is a 230gr with 835 fps = 359ft lbs.MetalMan said:According to www.taurustactical.com ALL Taurus mfg. firearms are built to use SAAMI spec +P ammo. My PT 145 Pro is always loaded with either CorBon DPX,Hornady TAP or CorBon PowR Ball .... all +P.
I believe this is more than a comment on the part of Taurus.It is more of a declaration from the manufacturer that +P ammo is 100% acceptable in all Taurus handguns.
Found that out the hard way! My very first handgun, an S&W M19, suffered a cracked forcing cone from a steady diet of Federal 125 grn JHP's. It did say .357 Magnum on the barrel and I didn't know any better at the time, being new to Handguns. Got it fixed at S&W then traded it for a WWII Walther P38, which I still have.Qwiks draw said:There are some incredibly high pressure rounds out there that are +P. Kind of like the difference between using hot loads in a Ruger .357 magnum versus a S&W model 19 or 66. The Ruger was built to take the steady pounding of the hottest .357 magnum loads over a long period of time. The S&W revolvers mentioned start to come apart or have troublesunder that same steady diet.
