From the serial, I'd even say it's a Z-Gun (ZHICAPA51? Z-Gun Hi-Capa 5.11?), but most internet searches of the serial turn up nothing.
I found a local listing, and it states the manufacturer as a 'Mag Foe'; http://www.pmhobbycraft.ca/MAG-FOE-Z...IZHICAPA51MAG/
Can anyone verify the company?
I mean, just for curiosity. We might find some relative redeeming quality in the pistol.
As for the OP, I'd say go with a WE or TM, just like everyone else. Sub-par kit means Sub-par performance.
