I LOVE just about everything about my PT-111. The only thing that gets me is the finger-pinching that occurs after every shot.
With the extended finger-rest magazines, there is a small gap between the grip and the magazine base. After every shot, when the slides comes forward to strip the next round, it pulls the mag flush with the grip, pinching my finger.
I mentioned this in the other thread, and someone was kind enough to put up a picture. Though, they mentioned that they had no such issues.
Other than that, I've only had one fail to fire that I credit to the ammo (older WWB).
I actually prefer the Heinie sights to the three dot on my PT-92, and love the size and feel of the PT-111 in my hand. I also dig the trigger of the new SA/DA-- feels much better than my PT-92 DA/SA.
I haven't shot too many similar pistols for comparison. The closest I can think of is the Sig P232, which I really didn't like-- felt too light, and had a "snappy" recoil.
The only other one I've shot and would compare is the Glock 23 in .40cal. The recoil definitely felt smoother on the PT-111, which I'd credit to 9mm vs .40. The trigger felt much lighter on the Glock, though I hated the plastic trigger safety. The Glock did feel great in my hand, but about the same as the Taurus. And, I definitely prefer the looks of the Taurus.
Disclaimer: I know it's sacrilege to compare Glocks and Tauri (and Sigs), but I haven't shot that many pistols, which I'll gladly remedy if you all would send me your Glocks and Sigs that you don't want.
