Click to blow your mind.
The general consensus (with which I agree) is that it's a novelty gun. I can totally see some garage gunsmith producing something like this in the Sixth World, though. Especially in LA.

Meh, there are plenty of cool guns that SR4 misses out on.

The Lemat Revolver - 9 bullets and underbarrel shotgun
The Lefauchex(sp) 20 round revolver with double barrels
McFairlain Tri-Barrel Shotgun
Combination Guns
TP-82 Russian Survival Gun (Pistol Shotgun - Space Program Survival Gun)
There are also some quad barrel shotguns floating around as well.

A few quickly clobbered together rules for weapon modifications.

New Weapon Mods
Stock Removal
Slots: -1
Cost: As Barrel Reduction
Concealability Modifier: -2
Recoil Modifier: +2

Additional Barrel
Cost: Base Damage Code X100Y /Barrel Max +2 Barrels on SA/BF weapons and +3 on Shotguns
Slots: -1 / Barrel [Slots -2 if weapon has BF/FA mode]
Concealability: +2/Barrel

Additional Rules
Break-Action weapons gains +1 Ammunition per barrel. Add+1 damage per barrel if choosing to fire more than one barrel at once.
-SA Weapons gains Short Burst / BF depending on amount of barrels
-BF/FA weapons add +1 damage when using BF/FA per extra barrel
-FA/BF weapons multiply their firepower by X barrels but also do the same with their recoil. Also, supermachineguns will run out of ammo fast – I leave it to the GM to moderate gunbunnies…

Enlarged Cylinder
The enlarged Cylinder improves a revolvers capacity with +50%.
Slots: -2
Cost: 1000
Bullets: +50%
Concealability: +2

Weapon Example

The Mob Enforcer (Elephant Rifle)
The rifle is a short, ugly and a brutal affair. Base on real life triple barrelled shotgun with a sawn off barrel and removed stock with a sensitive trigger.

There's already a mod that increases the capacity of a revolver. "Increased Cylinder," Arsenal, p. 152, "raises the ammo capacity of a cylinder from 6 to 8." That kind of leaves the Cavalier Deputy in an odd sort of limbo, but meh. I wouldn't let your version in unless it cost at least 3 slots, either. A cylinder big enough to offer a 50% increase in capacity would require serious modification of the frame, not just the timing mechanism.

One mod slot for a whole new barrel? (IMG:style_emoticons/default/smile.gif)

A friend sent me a link about this pistol yesterday, so I knew it'd show up here soon! Hehe. It certainly seems like a novelty, as OP said. If you did this in SR4, wouldn't the Sakura Fubuki's 'Metal Storm' mechanism be better?

+50% of a revolvers ammunition is +3 or a total of 9 bullets.

This one would indeed function with Increased Cylinder to give a total of 12 bullets (6+2)+50%. And yes, it DOES require a serious modification to the frame, that's why it costs 2 slots intead of the increased cylinders 1 slot cost. The only problem I see is that the modifications name should be a bit more spiffy.

Well, that is the metalstorm tech and we could probably remake that to several guns by adding barrels, give it electronic firing and then change loading mode to [b] as in barrel (not Break Action in this case).

Besides, having twin barrels beside each others looks...clunky, wouldn't it be better to have them above/below each other?

Well, not THAT much internal modifications are needed, more external work as you add a barrel that affects concealability as well. Check the links, adding a barrel to a hunting rifle isnt too much work - perhaps one should have it take additional (2) slots when you add it to weapons with SA/BF/FA and that they have clips since the loading mechanism is so different from a Break Action rifle.

This might also limit the full auto X3 barrel insanity...

Yeah, that was my thinking. It's not just a barrel, it's a fair bit of mechanism.

You basically need an extra barrel, extra trigger, and extra clip...3 mod slots?

More like modified trigger and clip, but yeah. If anything is an extensive modification, this is.

I just realized that any (b) loaded weapons automatically gets 1 or 2 extra barrels if you choose "Additional Clip" modification. I cannot find any other reasonable solution as they cannot 'switch' between clips or have any other storage place for the ammunition than the barrel of the gun.

1: Barrel loaded weapons plug their bullets directly into the firing barrel - they have no other place to store ammo
2: Since they double ammunition they must in that case gain one barrel extra per bullet.
3: Sakura fubuki (4 barrels) would end up with 7 barrels (+75%) since it is barrel loaded. It could be argued that the barrel length is increased on that weapon due to loading mechanism.

This would only work on (b) loaded weapons and is fairly expensive at twice weapon cost (elephant rifle would cost 12K with it).

Still, the Elephant Rifle would then (reasonably) be able to fire all four barrels at once with a +3P / AP-1, a fairly powerful hunting rifle for paranormal hunters who could probably modify such a beast into the 20K range.

Yea, any weapon with a modern loading mechanism (not break-action) should cost -3 slots due to the ability to fire automatic fire through triple barrels. They essentially become miniature gatling guns. Sure, it's -6 with 3 barrels but with a weapon that ALREADY might have smartlink, recoil comp and FA mode it's rather balanced.

The Jopp, guns without clips can't *get* Additional Clip. The description says it takes you from 1 clip to 2. (IMG:style_emoticons/default/smile.gif)

Nothing wrong with houseruling in 'equivalent' mods, but there's no reason to borrow trouble from the RAW.

That should teach me to work at work and not post stuff while trying to remember some half-remembered rule form a book (IMG:style_emoticons/default/grinbig.gif)

I just realized that this open up another can of worm.

Weapons with Magazines (M) or Drum (D) can never do that either then. The MG36 of today have the following options:
Magazine
Drum
Twin-Drum

The same goes for Extended Clip that also is restricted to Clip loaded weapons.

I think they've managed to warp the wording a bit to restrictive.

Im not trying to troll but I dont think that is what they meant. But I can see a problem with a revolver using twin cylinders...On the other hand...
CROTCHREVOLVER

I agree. Like I said, you can houserule in equivalents… when appropriate. (IMG:style_emoticons/default/biggrin.gif) I prefer to assume it's an intended balance restriction, but whatever works at your table, of course.

Is that a double drum, or actually 2 separate drums? Additional Clip gives you two independent ammo sources, so I can see it being a little complicated and restricted. And possibly they figured you didn't need more than a drum. (IMG:style_emoticons/default/smile.gif)

Never underestimate the (perceived) need of a gunbunny ^__^

The gun-bunny may not even be aware of his need until someone or something proposes the idea to him...

If you need more than two drums, just link a WHOLE lot of belts together.

"What the hell is THAT?" "Oh, I call it the Battle Pack. Been saving it for a few years just in case of a situation like this." "And what's in it?" "Ammo. 10,000 rounds of ball ammo with intermixed tracers for my HMG, and a feed system that keeps the belts from kinking." "Why the hell did you have this?" "Figured it was a good idea and I had a weekend free."

I love it when situations like that occur.


I've used either additional clip or underbarrel weapon mod (depending on the situation) at my table as an analog for additional barrels for breach loaded weapons like the yamato (?) [single shot 7P Pistol from arsenal] and other weapons. I havn't really seen any balance issues since ammo is still going to be a limiting factor, and reloading a breach weapon is still slower than smarklinked "clip" fed weapons.

The Hatamoto, and it's not breech/break-loading. It's internal magazine. I don't disagree with your point, though: internal mags are also slower to load, and Additional 'Clip' is 2 slots, 20 Avail, and doubles the weapon cost… seems fair.

The main issue is that it's safer for the GM to approve these on a case-by-case basis.

Agreed, but I do that for everything, even if its by the books RAW.

I think you may be confusing the SR definition of Clip with the RL definition of Clip (yea, it is a old standing "issue". Blame Hollywood).

SR (M) is internal (M)agazine, The kind found on most hunting rifles and similar. (SR4A p324)

As for (D)rum, that is already covered by the extended clip mod. It got a variant for 2 mod points that provides a drum option for SMG and assault rifle, that holds either 50 or 100 rounds depending on how "concealable" the user wants it to be (+2 dice for the spotter pr 50 rounds, meaning a assault rifle with a 100 round drum provides +10 dice). (Arsenal p150)

I think he meant natively Drum guns can't get 'Additional Drum' (not Extended, though they can't get that either—100 is enough!). It *is* important to keep track, though: 'box magazine' is 'clip'.
