Kang-Petrov Arms KPS-410 'Hallway'

The Kang-Petrov KPS-410 is a pump-action shotgun chambered in .410 bore with a six-round tubular magazine and a slim profile that makes it the most compact long arm in Kang-Petrov's catalog. The .410 bore is the smallest common shotgun caliber, producing minimal recoil and noise while still delivering a spread pattern of small pellets effective at room distance.

The Hallway is designed for people who need a long arm but live in spaces where even a 20-gauge shotgun feels excessive. The .410's gentle recoil and mild report make it shootable by virtually anyone, regardless of size, strength, or experience. The slim receiver and narrow magazine tube give the weapon a profile barely wider than a rifle, which aids storage and handling in cramped quarters. Kang-Petrov markets the KPS-410 as 'the apartment shotgun' — a descriptor that is both accurate and slightly depressing.

The weapon's effectiveness is limited by the .410 bore's modest payload. A .410 buckshot load contains roughly one-third the pellets of a 12-gauge equivalent, with proportionally less energy per pellet. At five meters, this is irrelevant — the concentrated pattern is lethal regardless. At fifteen meters, the pattern has thinned enough that target hit probability drops sharply. The Hallway knows its range and doesn't pretend otherwise.

tactical use

A minimal-recoil shotgun for close-quarters defense in confined spaces. The .410 bore produces the least recoil and noise of any shotgun caliber while remaining lethal at room distance. Effective only at very close range — the reduced pellet payload limits hit probability beyond arm's length. Best suited for operators who prioritize manageability over power.

cultural context

The Hallway is the shotgun for people who are afraid of shotguns. Its gentle nature makes it accessible to everyone, which is both its strength and its limitation. In a world where threats are increasingly armored and augmented, the .410 bore is a reminder that not everyone can afford — or physically manage — the weapons that the threat environment demands.

story hooks

A .410 slug from a Hallway hits a critical system component during a firefight, causing a chain reaction that does more damage than the round itself ever could. The shooter had no idea what was behind their target.
Kang-Petrov develops a .410 'smart shell' with a micro-guidance system that steers the payload toward center mass after leaving the barrel. The first prototype works perfectly. The second one doesn't go where it's told.

physical description

visual profile	A sleek, almost rifle-like shotgun with a dramatically slimmed receiver profile. The KPS-410 reads as purposefully minimalist — no tactical rail clutter, no oversized components. Its narrow silhouette gives it an almost elegant appearance compared to the brutish geometry of larger shotguns. At first glance, it could pass for a compact rifle until the pump action and muzzle spread reveal its true nature.
dimensions	Overall length: 94 cm \| Barrel length: 46 cm \| Receiver width: 5.2 cm (exceptionally narrow) \| Height with sights: 8 cm
weight description	Notably light and balanced — 2.0 kg distributed along the slim profile makes it feel almost delicate in comparison to combat shotguns. Handles with the ease of a large-frame rifle despite being considerably more compact. The thin magazine tube shifts weight slightly forward, but the overall impression is of a weapon designed to be shouldered for extended periods without fatigue.
primary material	Aluminum alloy receiver with hardened steel barrel and bolt. Synthetic composite furniture throughout — no wood, no excess steel.
finish	Matte charcoal gray on receiver and barrel with slight brushed texture to reduce reflection. The magazine tube has a subtle crosshatch grip pattern. No chrome or polished surfaces — entirely utilitarian satin finish that suggests this is a weapon for people who live in small spaces and want minimal maintenance.
color scheme	Matte charcoal gray as primary, with muted gunmetal accents on the barrel and action components. Grip panels in black tactical polymer. Minimalist aesthetic — no unnecessary color variation or branding flashiness.
grip texture	Crosshatch-pattern tactical polymer with subtle raised grip texture. Not aggressive — designed for people of varying hand sizes and strength. The pump handle has the same pattern, creating intuitive tactile feedback for the action cycle.
distinctive features	Exceptionally narrow receiver profile — noticeably slimmer than even compact rifles Simple bead front sight with no rear sight (minimal sightline clutter) Tubular magazine tube extends only slightly past the receiver, eliminating the typical long magazine protrusion Pump handle is set slightly lower than standard shotguns for apartment-friendly ergonomics Muzzle crowned with a simple recessed design — no muzzle brake or compensator Safety lever visible on trigger guard in bright secondary color (tactical orange or blue) — stands out against matte finish Minimal ventilation ribs on barrel — purely functional, no aesthetic flourish Chamber marking '.410' stamped directly into receiver in small, clean serif font
manufacturer markings	Kang-Petrov Arms logo (simplified geometric mark) stamped on left side of receiver in minimal relief. 'KPS-410 HALLWAY' engraved in small, clean sans-serif font below the logo. Serial number stamped on the bottom of the receiver in standard government format. No other branding — the entire aesthetic rejects salesmanship.
condition typical	Generally well-maintained due to minimal recoil creating less mechanical stress. The narrow profile makes it easy to keep clean in cramped living spaces where storage matters. Usually shows minimal wear unless subjected to heavy use — the aluminum and synthetic construction ages gracefully without the dramatic corrosion patterns of steel-heavy designs. If worn, wear appears as subtle scuffing on edges and the safety lever, never deep damage.

Product photograph of the Kang-Petrov KPS-410 'Hallway' shotgun displayed on a dark charcoal surface next to a cybernetic gloved hand (chrome knuckles, neoprene palm) for scale. The weapon's ultra-slim profile is emphasized against a dark backdrop. Dramatic side-lighting from the left highlights the matte charcoal finish and minimal receiver width. The pump action and bead sight are clearly visible. Background shows faint GLMZ neon reflection (cool blue-green) on matte black, evoking cramped urban apartment living. The safety lever's bright tactical orange stands out against the minimalist gray. Cinematic depth of field, shallow focus on receiver detail. Neo-noir product photography aesthetic emphasizing the weapon's function as a utilitarian home-defense tool rather than tactical hardware. --ar 3:2 --v 6
