The Comet is a simple blowback, open-bolt submachine gun designed from the ground up to be reliable and controllable in full auto. Unlike the Mod 2 Valturia, this weapon adopts a form factor much closer to that of a rifle for ease of handling, with a conventional buttstock and 32-round double-stack/double-feed box magazine that feeds from the bottom of the weapon. Charging handle is on the right side with a notch at the rear for use as a bolt hold-open and safety.
The weapon has an 24cm barrel screwed into a barrel shroud, and a two-point sling attachment system. Provisions are made for the optional addition of a bayonet lug for the weirdos who want one on a submachine gun and radium sights for use at nighttime, should the purchaser request them. A particular emphasis is placed on the magazine assembly, with interchangeability of the magazines and reliable feeding being top priority for the design team.

Difficulty: 0Your first proper submachinegun is sensibly a simple blowback, open bolt design, probably the simplest way of designing the weapon. Unfortunately, your engineers spent a bunch of time playing around with radium paint for the prototype sights, and then some of them got sick for a while and couldn't work too. This meant that most of the gun didn't get enough iteration and testing, particularly the new double-stack magazine. Radium sights were canceled after this incident.
Comet Submachine Gun: This is a simple blowback, open-bolt automatic weapon, chambered in 8mm Behrens. It's about the size of a carbine with a rifle stock, and the receiver is a lathed cylindrical piece which contains all of the working parts. There is a long spring housing behind the receiver, and a 32-round double stack magazine sits below. The barrel is 24cm, a small portion of the gun's overall length, and it sits in a shroud of sheet metal with drilled holes. It fires from an open bolt, so the trigger simply holds the bolt open when not depressed. When the bolt slams closed, it chambers a round and fires, and there is a charging handle on the bolt. A safety notch can hold the bolt in the open position. It's not compatible with existing Behrens magazines, and feed through the magazine is poor. It jams relatively often. Simple feed jams are not hard to clear, but occasionally a cartridge becomes disoriented inside the magazine which could take minutes to fix. There are occasional issues with burst brass which becomes stuck partially in the chamber as well, the firing pin may be prematurely igniting rounds. Furniture includes simple notch sights, a wooden shoulder stock with a rear pistol grip and flat foregrip under the receiver, and a detachable bayonet which screws into place. Costs 37 credits per batch.
