I have a PT 1911 (45ACP) and was looking at getting a PT709 for summer carry, and 40 S&W's are out of the question due to bad wrists. Then I was looking at the PT145 (I like the 45ACP) single stack, and saw an add yesterday for the PT745 with specs. Looks like the PT745 is very close to the PT145 with a few differences. So I am looking for a little input from those that may have shot and/or ccw both.
