So I was doing some xmas shopping for my younger brother last week and came accross this bb gun. It goes from Hand gun to "tactical carbine" without permanent alteration to the hand gun. https://www.youtube.com/watch?v=IVnaxsoOci0 It got me thinking, they should make something like this out of more sturdy materials for real hand guns. After doing some looking, I found exactly what I was after! Keep your CCW pistol, and be able to readily convert it to a PDW type weapon! Unfortunately though, this would still make your pistol an SBR subject to NFA regs. https://www.youtube.com/watch?v=yMaz4qtLQ2o
