Well lets see...
I've owned a PT99 since 1986 with literally thousands of rounds through it. Factory mags, Mec-Gar mags, even the shitty Pro-Mags. Not a single issue...ever.
I also own a PT145, 24/7 OSS .45ACP, and a PT738 TCP, factory mags in those as well. The only issue with any of those 3, is that the TCP has had issues ejecting a live round when clearing the chamber if I don't fire all the rounds. Specifically...cheap ball ammo. No issue with the Ranger T stuff.
My daily carry is the PT145 with Ranger T series ammo. I've never had an issue with this firearm, of any kind. I trust mine, and my wife's life to it.
