The grip circumference on the 745 is obviously thinner than the 145 and 24/7 being it is a single stack. The 24/7 has "ribber" grips which the other two do not offer. The 24/7 also comes with a compact mag and a hi-cap mag (where legally available).
Internally, they are nearly identical.
I have a PT145 and it is a pleasure to shoot. The 45 ACP is a very controllable round in most guns.
