Marushin Derringer Black heavy weight X cartrige 6mm

Nice Derringer in Black Heavy weight finish 

We recently discovered an issue with the X-Cartridge versions of the Derringers, after running out of our 134a gas stock. Both BBs can be launched at the same time, which isn't supposed to happen. The issue appears to affect only the X-Cartridges; the leading theory at the moment is that the pressure is too high for the seal that the cycling system between the barrel and the BB retention system can provide.
