I researched them quite a bit. Probably went through 20-30 reviews.
No, it does not have a mag disconnect. You can fire without a mag in it.
I don’t like to have to mess with a safety for my carry guns. (My KelTec P11 doesn’t even have a safety. I carry my CZ-82 with the hammer down. It’s safe to do so with the CZ-82. I shoot the first shot DA and rest are SA.)
The PT111 has a trigger safety and a long trigger pull. Therefore, I think the manual safety is unnecessary. Like many people, I just won’t use it. I’ll carry and shoot it like a Glock.
But if you don't like it, you can just send it on to me, eh? /smile
