It's been many years since I last saw MAB PA-15's being imported (I think the distributor back then was Howco). I had one about 30 years ago and was impressed by its built-like-a-tank construction, ability to reliably cycle with any type of ammo (rotating barrel design), and by its inherent accuracy.
It was also one of the heaviest pistols I have ever owned (I believe even the thick base plate on the mag was a piece of machined steel), and best sutied for range work as I really didn't want to lug all that weight around. I eventually sold it because I couldn't find any spare parts or magazines for it.
