I have a PA63 in 9X18, although mine must be an odd variant because it has a black frame, instead of just in the white anodized aluminum. It has fed and fired all the rounds I have put though it, which isn't enough to be comfortable with it. Mine was $125 and it judging from where the finish was worn, it was mostly holster wear. The trigger actually smoothed out after I dry fired it a bunch. The trigger is horrendous. The other day I was curious on how heavy it actually was, so I used a digital fish scale, which is not the right tool, but I did get 24lbs on DA. I am getting a lighten trigger spring and two new recoil springs(13 and 15) from Makarov.com. 4 used mags too. With the current recoil spring it really hits the hand hard and throws the brass(read steel!) like 20ft.
I would definately carry a Glock 23 instead of a PA63. 10X40S&W, slide is actually shorter than PA63, although grip is like .85 inch longer. The main reason I will keep it is that it was cheap, I wouldn't get anything out of it if I sold it, ammo is cheap, it is reliable, and it will fire if shoved up against something. It is a throw away that will do the job, seven shots of 95 grain 9.3mm bullet@1050 second isn't something to laugh at when it is coming from < 3 feet. Chrome bore lets you treat it like shit too.
Go with a mini glock or something, although a lot of people carry Maks.
