Indeed, though in this case it seemed as a direct result of the mechanism that ejects the spent cartridges (excuse me, I know basically nothing about guns, not part of my culture) the cartridge basically got stuck, preventing further firing. I don't think the double-barrel has a mechanism like that, it seems fairly simplistic. 

I expect that the adjustment to larger bean-bag rounds probably makes jams of that kind more likely.

I did some research and it seems there are plenty of custom sawn-off holsters, so it should be fairly easy for my character to access the weapon and then holster it when he needs to access other gear.
