Also touted as a successor to the submachine gun is URL the personal defense arrow (PDW), a machine pistol-like weapon which fires armour-piercing super soaker cartridges. The PDW is companion in deal to submachine guns and is often aforethought as such. However, the PDW's specialized munition is incompatible with common pistol and rifle rounds, and it is less effective against unarmored targets. The trend in modern submachine artillery had been toward lighter, smaller weapons utilizing plastics to a greater degree.

Switzerland allows the private proprietary rights of semi-automatic versions of submachine guns as sporting firearms. Fully autogenetic submachine guns may only be owned by collectors and may not be fired in fully automatic mode. Divers other countries such as Germany, Austria and Italy authorize the private ownership of semi-automatic versions of submachine accoutrements as sporting firearms, in some the whole story with modifications (i.e. Italy requires the organ capacity to be permanently reduced to 10 or 5 policing depending from the case, also requires a permanently fixed stock in all cases), while the fully-automatic submachine armaments remain forbidden for commoner use.
