Had one of those PT145's years ago and it discharged with the safety on. Took t too my gunsmith for a look see. Wrote up a paper for me on the problem. Sent the gun back to Taurus. They denied their was a problem. I told them I had a sworn statement from a gunsmith as to the defect with the gun.
The lady I spoke with was shocked and said "why would you do that". Told her because I had dealt with Taurus before. They sent me a new gun. I never took delivery of it used it as a down payment on a SIG. Don't trust Taurus plan and simple.
The PT145 was very accurate, great in the hand, and a nice gun. But with a serious flaw. Shame Taurus had had some nice designs. Just very hit or miss and customer service is not what it should be. I know they have a "lifetime warranty". Good luck with that!
