GURPS Guns: Luty 9mm SMG

A more unusual gun this time, ideal for an After the End game. Information about this weapon is hard to find, so more guesswork than usual went into the numbers. Don't try to build one of these things yourself; they are not only illegal almost everywhere, but also probably unsafe to both build and shoot.

Luty 9mm SMG, 9×19mm (UK, 1998-)

Philip Luty designed this extremely simple weapon as an act of protest against restrictive gun laws in the UK. Unsurprisingly, the protest resulted in him spending much of the rest of his life in prison, but the instruction manual he wrote for constructing it was published and distributed widely enough that copies have been made around the world, mostly by criminal groups. The design was intended to be built from commonly available materials with only an angle grinder, blowtorch, electric drill, and some hand tools.

It is a straight blowback operated smoothbore weapon, firing from an open bolt, with neither sights or stock, so accuracy is poor. It also lacks any form of safety. The single-stack magazines are also hand-made.

As an illegal (LC 2) item made in small workshops, price is hard to estimate. For the purposes of crafting and invention rules, $200 for the gun and $50 for the magazine seem reasonable, but actual examples are said to be sold at around five or six times that price due to the danger of trading in them. Quality will also vary considerably, with many being entirely unsafe to use, while others may be relatively reliable. A typical example is probably 'Very Unreliable', malfunctioning on a 15+. Although designed at TL 8, it needs no technology which wouldn’t be available at TL 7, so could be treated as a TL 7 device for crafting and invention rules.
