I don't think anyone would want to really
I actually threw an air pistol in the bin once because it was just sooooo cr*p..
it was (i think) a manuarm or something similar, the one with a trigger guard that went over the whole of the hand...
the piston was a manky die-casting (zinc alloy or rather more aptly named, monkey metal )
it was the most awful airgun that i'd ever seen
