I have a VP70 I bought many years ago w 4 mags. Ancestor to both the Glock and the Hi Point, w a polymer frame and straight blowback (albeit with a fluted chamber) and a trigger like a staple gun. That doesn't even get into the odd mirrored front sight, where you hold on the shadow between the mirrored surfaces.
I admit, I bought it to complete my Aliens collection, partially. Now I have a short Ithaca 12 ga, the VP and a Smith auto. The 18 round mags are nice, too.
I have seen the 3 round burst version w the stock, and really have no urge to get or shoot one. Many better full auto fish in the sea. Fun to get out once in a while, though.
