SuperMagnum Model 600

The SuperMagnum Model 600 is a series of large caliber revolvers designed and manufactured SuperMagnum Inc. It is noted as being one of the largest commercially available revolvers (and respective cartridge) since Smith & Wesson’s .500 cartridge and revolver from the 21st century.

Due to its size, weight and very high recoil, it was never formally adopted by any militaries, though some soldiers in elite sections did use the pistol. It was primarily marketed to the civilian firearms market, and proved to be popular with the likes of bodyguards, ship crew and bounty hunters alike.

It became a collector’s item for its unusual features, extraordinarily powerful cartridge and considerable customisability from a revolver.

Description
The Model 600 is a double-action, centre-fire, .60 caliber revolver chambered for the .600 Magnum Bolt, developed by SuperMagnum Inc. The revolver was designed in the mid 2250s, but manufacturing techniques at the time were incapable of producing strong enough materials to handle the massive pressure of the Bolts.

Attachments
Just about every factory model of the M600 was equipped with Universal Attachment Rails along the top of the frame, and the underside of the barrel. A grove cut into the pistol grip allowed pistol stocks to be attached.

SuperMagnum themselves did not produce any attachments for the M600 since their production plants focused on ammunition and guns. Instead, the UARs on the weapon allowed owners to customise their revolvers for whatever purpose they may need it for.

And whilst not rated for use with them, some owners are reported to have attached underbarrel grenade launchers to their pistols

Safety
The Model 600 was noted for having safety features, something rather uncommon on revolvers. A traditional fire selector (S for Safe, F for Fire) was present on the frame just in front of the cylinder. This selector switch controls a small rod inside the frame, which blocks the trigger mechanism, and holds the hammer in place.

A secondary safety feature was the ‘hammer safety’ - a feature that, whilst not unique, was popular with the Model 600. This mechanism requires the user to cock the hammer on only the first shot - follow-up shots are double-action, though single-action firing is still possible. This feature was added to reduce the chances of an accidental or negligent discharge, as the sheer power of the .600 Bolt could cause serious damage or death. Additionally, because the hammer had to be cocked, it acted as confirmation from the shooter that they are ready to fire

B-Spec
The B-Spec 600, (literally Big-Specification) is the largest and 2nd most popular variant of the Model 600. Because of the much larger frame, the cylinder was also able to be expanded to 9 shots. This did however, cause it’s weight to increase drastically, from 2.24 kg (M-Spec) to 6.35 kg. Coupled with the lack of recoil compensation system, the B-Spec’s potential market was limited to only those who had the ability to wield such a weapon.

The former points were rather negated by the fact that the large frame model was manufactured with SPARTANs and users of cybernetic limbs in mind. Statistics from SuperMagnum showed the B-Spec to be quite popular with SPARTANs as the .600 cartridge was very well suited to disabling energy shields

C-Spec
The C-Spec 600 (Compact) was a small, snub-nose version of the M600. Because of its comparatively tiny size to the B-Spec, or even the M-Spec, the cylinder's capacity was restricted to 4 rounds. The C-Spec also lacked the underbarrel UAR, and had no forms of recoil compensation which made the already very light frame, almost unusable. The C-Spec was quickly pulled from production after only 7 months of availability.

M-Spec
The M-Spec 600 (Medium) is a medium sized Model 600. It was the most popular variant of the M600, as it was more similar to a standard sized revolver. Compared to the B-Spec, the M had a 4” shorter barrel, was 2” shorter in height, and weighed  3.5 lbs less. The mid-frame model was equipped with an advanced recoil compensation system which allowed non-augmented, or 'organics' to use it.

Daniel Cain (as Murdoc Chambers) owned an M-Spec Model 600 which he most commonly shot with his left (cybernetic) arm.

600 Carbine
A carbine version of the Model 600 was manufactured for a limited time. It was a B-Spec B600 which had a permanently attached stock, an elongated barrel, and a 3.5” compensator on the end. It was only manufactured for a limited time, and reportedly cost 6250 Credits (for comparison, the M and B-Specs cost 4000 and 9500 credits respectively)

The Carbine version proved unpopular and was subsequently discontinued.

Ian’s Custom 600
Ian Cain wielded a customised B600 for several decades from the 25-26th centuries. It was a B-Spec Model 600 equipped with a muzzle brake, reflex sight, horizontal grip, and a quick detectable stock fitted to the pistol grip.
