DESIGN:
The ZLD 587 fires the 9 mm Parabellum cartridge (though some variants fire .22 LR, .41AE, or .45ACP) using an open-bolt, blowback operated design. Also available are 20, 32, 40 and 50 round magazines- 9 mm Parabellum, 10 round magazines- (.41) and (.22LR), and 16 round magazines- .45ACP. All of the above are manufactured by UNSC GMFacility. Other high capacity magazines exist (e.g. 50 round magazines and 100 round drums in 9mm) which are manufactured by facilities other than GMFacility (such as Vector IV Facility). It is made of stamped sheet metal and has relatively few parts, making it easy to strip for maintenance. It features a magazine held within the pistol grip, allowing for intuitive, and easy, reloading in difficult conditions ("fist finds fist"). The weapon also features a grip safety, making it difficult to fire accidentally. Despite the grip safety, the ZLD is notorious for slam-firing when dropped or exposed to sudden shocks. When decocked, the ejector port closes preventing entry of dust and dirt. Also, the bolt wraps around the barrel, allowing a heavier, slower-firing bolt in a shorter, better-balanced weapon. This is technically known as a telescoping bolt. Although the ZLD is generally a highly effective weapon, it is prone to jamming in desert environments because of sand, a fact which possibly contributed to the UNSC DFIC (Desert Facility for INTEL on Covenant) decision to phase out the gun. The grip-mounted magazine gives the ZLD a highly distinctive, instantly-recognizable profile. In such portrayals, the weapon is often fired one-handed (especially the Mini- and Micro-ZLDs) and in some cases even as a pair of weapons, one in each hand. While it is possible to fire an ZLD one handed, it offers less control over the weapon leading to less accurate fire, a problem that would be amplified by simultaneously firing a pair of weapons, one in each hand.
Added Specifications. The ZLD 587 can be added a scope, silencer and laser.
VARIANTS:
There are several smaller variants of the ZLD 587 SMG
Mini ZLD 87: 360 mm (14.17 in) long and basically a scaled-down version of the ZLD 587. First introduced in 2540, It comes with a side-folding stock and retains a small forward handgrip. The Mini ZLD 87weighs about a kilogram less than the ZLD 587 when unloaded. The Mini ZLD 87 has a rate of fire of 950 rpm, or about 16 rounds a second.
Micro ZLD 37: this ZLD is still in testing Facilities, because the Marine CORP find it to dangerous since it has a dangerous unstable maneuvering. The Facility is testing it with the Spartans. At only 250 mm (9.84 in) in length barely larger than a standard pistol and about as small as the original ZLD 587 design could be made. It fires from a closed bolt position and has a side-folding stock similar to the one on the Mini ZLD 87. The forward handgrip is completely eliminated. First introduced in 2548. The Micro ZLD 37 weighs 2.2 kilograms less than the ZLD 587 when unloaded and fires at a rate of 1250 rpm, which can unload the 20 round magazine in 0.96 seconds.
Para Micro ZLD 37: designed specially for counter Hunter units. It was recently developed by the GMFacility and is in use by the DMCIC and the Navy Anti-Hunter Team. It has a side-mounted charging handle, a provision which makes room for top and bottom-mounted Picatinny rails. It has an angled pistol-grip to accommodate a 33-round GWL18 magazine.
ZLD Pistol: a semi-automatic version of the Micro developed for The Marine CORP Externally, it is distinguished by not having a stock or a recoil compensator.
ZLD Carbine: a semi-automatic version of the full sized ZLD 587 SMG, with a longer 400 mm (16 inch) barrel. Was also generally available for The Marine CORP. New ZLD Carbines are still being Manufactured in the Cairo Mac Station.
The unrelated Inram MAC-15 is often dubbed the "Marine ZLD" because of its similar style of use.
FUTURE DESIGNS
Sniper ZLD 47: The Sniper ZLD 47 is designed as the original ZLD 587 except for a stand up Biped mounted in front. The Sniper ZLD 47 is bigger in size and weight. (No accurately design because the GMFacility barely started working on it.) It has a slower RPM but powerful bullets. These bullets were made to deactivate shielding mechanisms in Covenant armor, vehicles, and structures.
