Well, I have an AB-10 and its actually a pretty decent pistol, for the money. It functions well, is more accurate than you'd imagine (even with its horrid sights), and it's just plain fun. Of course it's heavy, awkward and silly, but it's not supposed to be an HK P7 now, is it?
It was an impulse buy that I just had to have in my collection before it gets banned as well.
For about 200 bucks, it's a fun gun that actually works (as opposed to another gun in this category, the 9mm SWD MAC-11 knockoff. Yuck.).
All the best!
