Are sawn-off shotguns dangerous for the user?
Shortened barrels on shotguns does make them terribly effective out to about 25 yards. That’s the idea – it’s a weapon meant for close encounters of the unfriendly kind. And no – cutting down the barrel of a shotgun does not increase the likelihood of it bursting in the hands of the shooter. One can shorten the barrel of any shotgun, but in pump-action and auto-loading weapons, that also would sometimes require altering the area wherein added rounds are kept – the tube beneath the barrel – which in turn would reduce the number of rounds one could cycle through the weapon before having to reload.
