Pulling a double action trigger will only operate the hammer and allow you to fire the pistol from a hammer down position. It will not load a round from the magazine into the chamber. You must cycle the slide by locking in a loaded magazine pull the slide all the way to the rear and let go, and by this I mean remove you hand with the slide all the way back and let the slide do all the work.

Three Possibilities:
1. The manufacturer's sticky anti-rust grease, on the feed ramp or in the magazine, is hanging things up. Clean everything with solvent, and then lubricate with just a little oil.
or
2. The feed ramp is rough, and catches the bullet's nose. Shoot 300 rounds, and the problem will clear up on its own.
or
3. The magazine's feed lips are badly shaped. Try another magazine. (You should have at least three of them, anyway.)

Might I suggest taking a NRA basic pistol course? You've got the gun, which is great, now you need to learn how to use it. There is a wealth of information on this forum and by all means keep asking questions, but as a beginner, you might be better served with some hands-on instruction from a certified instructor. You'll learn safety, operation of your firearm, and how to shoot properly, and then with practice, accurately.

Out of curiosity I inquired about the capacity of the pt-145. To my surprise the 40 cal and 45 cal versions both hold 10+1 in a flush mag and the 9mm version only holds 12+1. I'm not sure but I don't recall any manufacturer equally loading 40cal and 45cal capacity in the same platform(perhaps a wider or longer grip on the 45) and just having 2 extra rounds in a 9mm, just seems odd but oh well.

You know what a doctor would say.....just put 1 less round in the mag............
