The KZ Type 29 Armor Service Pistol is used by the Star Army of Yamatai.
With the possibility of Nekovalkyrja in armor acting as dedicated ground troops, especially in urban settings, Ketsurui Zaibatsu considered developing a weapon that would go well with the Ke-M4-W2901 Light Armor Service Rifle. It was to be a closer-range weapon, focusing on packing most of its punch within a 100-meter range, but still able to damage armor.
Using that broad idea, commanders and consultants drew up specific parameters the weapon had to meet:
Size: No more than 350 mm long, 200 mm tall, and 30 mm wide
Weight: No more than 6 kg
Capacity: At least 50 rounds
Damage: Enough to damage or injure an M1 Phalanx
Mounts: Harpy, Daisy
Entered service: YE 29
With that criteria in hand, KZ's designers came up with a weapon that was based off the LASR's frame, but smaller and lighter in all dimensions, coming across as a compromise between a machine pistol and a submachine gun. Its most important asset, however, is its low production cost.
It's a short-range weapon, designed to blast holes rather than rattle or pierce as the LASR does. Though it's a long weapon, its light weight makes it easy for an armored pilot to lift it and use it. The HESH rounds are important to its role: Armors can manipulate when the rounds explode. Don't expect this to be a makeshift sniper rifle though; accuracy of the round might be good, but the gun itself is built to be compact.
Damage: ADR 2
Range: 100 m effective; 500 m maximum
Basically, field-stripping is easy. There really is nothing to clean that's produced by the gun; cleaning out the barrel and trigger group's done by dropping the magazine, pulling the trigger, pushing the safety and the fire selector up, and pulling on the charging handle, which will drag the entire trigger group out in one neat package. The barrel can be unattached from there.
This one's tough. This is the initial inspiration. However, I wanted to put my own spin on it as well, and mixed it with a favorite of mine, the Steyr MPi 69. But the grip angle is the same as the LASR, and it looks like a LASR in general appearance. Which confuses everyone, I know. Just imagine it to be most like the Zero Buster, with the stock being collapsible instead of fixed, and give it a more pistol-like appearance and barrel, with a charging handle on top instead of sights and stuff.
For the sake of having some detail, at least, note that it has polymer furniture and the rest is titanium or (occasionally) steel.

Firing Mechanism: Round is pushed into barrel's chamber from the magazine by pulling back the bolt (via the “dorsal” charging handle) on the gun and letting it be magnetically pulled back toward the receiver. Magnetic pulse is charged behind the round by this action. The bolt will cycle the battery and charge another pulse.The magnetic pulse is then fired behind the round once the trigger is pulled, sending the round between the differently charged rails inside the barrel of the weapon. The moment the pulse is fired, it pushes the slide back, recharging the pulse projector and bringing a new round to the front of the magazine to be stripped and put into the chamber. Cycle repeats.
Special folding stock: As the weapon is modeled after a machine pistol, but with the ability to be an SMG, a special stock was developed. In essence, a metal “bar” extends from the back of the weapon. The bar is only a couple inches long; it is attached to two metal rails that follow it; these are collapsible rails. From the bar folds down a collapsible metal stock. The stock looks to be, when viewing its profile, a rough quarter-circle. It is not a tough stock, but it is very compact, and can sustain most of the abuse of battle.
Recoil: Heavy. An unarmored non-Neko soldier attempting to fire this weapon would break their wrists. An NH-17R or NH-27 could fire the weapon, but it would be like firing a .50-caliber round from a compact pistol – only the first round would be controlled. Armored soldiers can control the weapon fairly well.
Safety: Located in front of the trigger in the form of a button; will disconnect link to magnetic pulse generator.
Fire mode selector: Just above the slide, and below the rear iron sight. Flip up lever for automatic; pull down for single.
Sighting: Mostly AIES reliant, as using the iron sights is a last resort only. Has no capability for added attachments, but does have a built-in light. AIES essentially guesstimates the line of fire based on where the gun is pointed, much like an invisible laser pointer would.
