I considered one after buying my PT-145. It is a great firearm. So the 380 initially made a lot of sense to me.
The problem: it's about the same size as the PT-145!
They are the same length. The PT-145 is about a quarter inch taller and they are essentially the same width.
So, 10+1/12+1 in 380 or 10+1 in 45acp? If I'm going to carry it might as well be 230gr vs. let's say 102gr.
I kept my NAA Guardian 380. It IS smaller.
