Do have a PT111 Mil/pro and do agree with other it's a very good gun, but it is a specialist gun as compacts and snubbies all are.Started out with the full size pistols and then moved on down to the much smaller guns. Took a while, but it was worth the wait and practice to become proficient overall shooting pistols.

If you are considering a Taurus there are either the PT92,911 series which are full size or near to that.
Or the 24/7 full size and then go with a 24/7 Mil/pro once the full size gun has been mastered.
92s are double action hard trigger pull followed by the light single action trigger pull for each subsequent shot. These are traditional actions and have a decocker to lower the hammer safely onto a live round without the round going off.Otherwise the hammer has to be lowered by slowly letting it down manually. The hammer could slip and set off the round.
24/7 and the Mil/pro family are of double action only family type of triggers.
It feels like a long light double action revolver trigger pull, of about 5 to 8 pounds, all the way through the pull. Takes some getting used to but with practice,technique, experience, and dedication, proficiency can be attained.
I will admit to a 9x19 bias. That's a personal decision. All the defense cartridges from the 9mm. to the .45ACP are excellent rounds.
The 9mm. is cheaper, less recoil,quicker shot to shot recovery,and it's easy on the shooter and gun.
Others will sing the praises of either the .40 S&W or the .45ACP. Good cartridges all.
