It looks just like the Rock Island Armory (=Armscor) model, even the markings/model numbers on the frame, if the pic is to be trusted. If so, it should be excellent for the price, although they've increased it to $419.99.
Rebate
Family Firearms and Atlantic Firearms have several models at good prices and no sales tax to GA.
I think these deals are being offered because companies are getting scared of the ATF coming after braces.
/r/gundeals is kind of obsessive about blacklisting companies. Global Ordnance is a major importer -- pretty sure they're not going to screw you.
I've used the AK mag. It works, mostly. PITA to load. Couldn't get more than 28 in it. (Never had any other mag I couldn't fill to capacity.)
It's very close to the same size as the original Shield, which is much smaller (narrower) than the Compact. Should be much easier to conceal due to less width.
