The 20mm pistol!

The 12 gauge revolver is the same idea as the Striker 12 gauge executed in a different fashion. The Striker is also a 12 gauge revolver. The difference lies mainly in styling and the Striker's cylinder being shrouded. The Striker has even been cataloged in a short version with no buttstock and twin pistol grips that would be about the same size as the Taiwanese gun.

Tell you what, I'll let you shoot it first, I'll be over there, way way over there behind those sandbags.

Did anyone test that thing (the 20mm) to see if it actually worked without killing the holder?
