On the pictures thread I found this gun:

Which linked to this article:
http://www.pascaleggert.de/ThorA1.htmlIt just
screams Shadowrun to me, and I decided I want it to exist in-game, as an expensive, rare and awesome SMG.
There are no standard firearm design rules in SR4, so I just decided to wing it. I created two versions, one that actually matches (reasonably closely) the specs given by the author, and one that is more in line with other guns in
Arsenal and the core book.
I'd like to get opinions and feedback before I hand these rules to my GM (and I'm an attention whore, so I just want to put this out there anyway).
Unbalanced version:Submachine Gun | Damage | AP | Mode | RC | Ammo | Avail | Cost |
iPEG Thor A1 | 5P | -1 | SA/FA | 2(3) | 50(c)* | 14F | 2,200¥ |
*Spare cMAG clip | | | | | 50 | 8 | 20¥ |
Thor Sound Suppressor | | | | | | 12F | 400¥ |
The Thor A1 is an experimental prototype submachine gun developed by the iPEG Corporation. Primarily an industrial design house with a reputation for sculpted lines, exceptional funtionality and high price tags, their newly formed arms division seeks to expand their market to wealthy and style-concious mercenaries, special forces and shadowrunners. To that end, the stylish and powerful Thor was designed to meet the needs of those willing to pay for the best. The body is high-density plastic, and the frame and internal workings are titanium, giving it unprecedented reliability, and allowing it to handle assault rifle ammunition for increased penetration, though it still uses SMG ranges and skills.
The Thor features a special firing mechanism that grants two points of recoil compensation, and a folding stock and foregrip that can be deployed together as a simple action. It has a top-mount that can handle any standard accessories, but no under-barrel mount. The barrel mount can handle most standard accessories, but it cannot accommodate a sound suppressor other than the one specifically designed for it without retooling -- taking an Armorer+Logic(2) test and voiding the warranty. If the custom sound-suppressor is equipped, it provides an underbarrel mount for an additional accessory, but increases the concealability modifier by +2. It is also available with an internal smartgun system (+500¥). This is a distinctive and uncommon weapon, and gives a +1 dice pool modifier to any tests to remember the weapon or its wielder.
