New craftable weapon - Luty SMG

[Razzberry8492]

It came to me in a flash of inspiration.

The Luty SMG, for those who don't know, is a pretty junky full-auto 9x19mm smoothbore SMG, made by a British dude at his home - it's the most complex firearm you could make outside a machining shop.

Assembly is pretty complex and spans more fields than just scavenging alone. As well as needing to know how to build it and acquire the materials, you'll also need to know chemistry and ore properties, as well as how to evade Security and how to bullshit your way out of searches.

There are four major components.

Firing pin:
Metal rod (preferably high Density).
The metal rod's Density affects the durability of the resulting weapon - if the firing pin breaks, the weapon is useless.

Handmade 9x19mm rounds:
Metal sheets crafted into 9x19mm hulls, with Black Powder propellant (welding fuel or anything else won't cut it) and metal scrap as the projectile (no glass, plasmaglass, bone, or potato).
It makes ten rounds, and you have to load it into a magazine first. It also fits in the zip gun.

Magazine:
Metal sheets and a small coil (preferably high Hardness).
The magazine spring's Hardness affects the chances of the weapon jamming - lower Hardness means more jams.

Luty SMG:
Metal sheets (preferably high Density), a small coil (preferably low Hardness), a firing pin, and a metal rod.
Load with a loaded magazine and fire. Needs two hands, fits in a backpack.
The metal sheets' Density affects the chances of the weapon catastrophically malfunctioning - exploding, becoming useless, and injuring the user.
The small coil's Hardness affects the chances of the weapon jamming - higher Hardness means more jams.

It takes quite a lot of time-consuming and conspicious legwork, it's weaker than a factory-made weapon, and it can betray you if you make it out of the wrong materials, but in the end, you get an SMG - something you can really defend yourself with.

Edit: after reading Expedient Homemade Firearms, I just realised that Mr. Luty specifically wrote to use metal tubes, not sheets. Oopsie!

But it doesn't matter anyway, we can still use sheets. Obviously our spacemen can bend metal into shape with their bare hands - Mr. Luty would be proud!

Im always for more craftable weapons on station. Especially shitty craftable guns.

[RSOD]

one concern is the firing pin — will the gun be able to be taken apart / put a new one in when it breaks?

[Mikeistaken]

im worried that it might be made too powerful for being able to be crafted, however with some balance configurations this might be a welcome sight on the station

To my knowledge all craftable firearms and bows are single shot weapons such as the slamgun, the zip gun or the bow all take some kind of action to reload and fire, each with benefits and disadvantages I think the 3 balance each other out really well, I don't think there's a need for a fully automatic craftable weapon, for my opinion and only in my opinion when it comes to balance craftable weapons are in a good place.

Wouldn't mind a 9mm syndicate SMG that traitors could spend traitor coins on though.

I am all for more craft able weapons junk weapons for staffies to make. More options for crew to fight with would make things more interesting.
(obviously would need to be balanced this kind of weapon should still be considerably worse then what a traitor can order/sec equipment)

There could be a case in either direction. I initially imagined it as "if the pin breaks, it's over for the gun", but there could also be the possibility of replacing the firing pin. It's not something one could do under fire.

Obviously, if the weapon has a catastrophic malfunction, then there's no coming back from that.

Of course, yes. Only a 20-round magazine, the fire rate isn't that high, it's a little inaccurate because of the smoothbore barrel, and the gun doesn't hit particularly hard. That, and the reliability issue.

Depending on balance, it might also be locked to being a two-handed weapon, on account of its considerable weight. It can definitely fit in a backpack though.

But in the end, it's an SMG alright. Put in the legwork and it's a decent reward.
