Rexio Arms

Rexio Arms is the trade name used by Argentine manufacturer Lasserre S.A. for a line of compact break action “pistolones” and survival guns. These single and double barrel handguns are chambered for .410 shotshells, .45 Colt, and in some variants .22 Magnum or .22 LR combination barrels. Often imported into the United States under names such as Super Comanche, Rexio firearms earned a following as simple, affordable tools for small game, pest control, and last ditch personal defense. Their straightforward construction, interchangeable caliber options, and distinctive look keep them interesting to collectors and shooters who like unconventional shotgun pistols.

Compact Shotgun Pistol Accuracy

Rexio “pistolones” are built around fixed barrels and simple brake action mechanisms. The Rexio Standard and related single barrel models use 250 mm barrels that provide a useful sight radius and enough length to keep .410 slugs and shot loads on target at typical small game distances. Adjustable sight variants in .22 Magnum give shooters finer control over point of impact, while the combination .410 and .45 Colt versions allow owners to match ammunition to the task. Within their intended range envelope these compact guns can deliver practical accuracy on rabbits, birds, and close range targets.

Utility And Small Game Use

Rexio products were conceived as working guns for Argentine shooters who needed a simple firearm for farm use, pest control, and casual hunting. Single shot .410 pistols, double barrel Super models, and fold stock survival guns all lend themselves to tasks such as small game harvesting, anti snake work, and general homestead duty. Local users often favored .410 slugs in defensive roles due to muzzle energy roughly comparable to service pistol cartridges, while still having the option to load birdshot for field use. The same simplicity that suits rural chores also appeals to owners who want a straightforward tool for informal shooting.

Simple Break Action Durability

Early Rexio frames were cast from Zamak alloy to keep costs low, with steel barrels and internal parts. Later production reportedly shifted to steel frames for added strength in some models. The break action design keeps the parts count modest and makes inspection, cleaning, and basic maintenance easy for owners with minimal experience. Although Zamak frames are not intended for high round count abuse and can crack if mistreated, reports of catastrophic failures are rare. For typical use with appropriate ammunition, many examples have stayed in service for years as functional utility and novelty guns.

Product Focus

Rifles

Rexio did not concentrate on traditional bolt action or semi automatic rifles. Instead, the company extended its break action concept into long barrel survival style firearms that blur the line between pistol and carbine. The fold stock “arma de supervivencia” uses an over under barrel set combining .22 LR and .410 or a .410 only configuration, paired with a metal folding stock that creates a compact package for storage and transport. These survival guns retain Rexio’s dual hammer and single trigger layout, with a selector that lets the shooter choose which barrel fires first. With their longer barrels and shoulder stock, they behave much like light combination rifles and lend themselves to small game hunting, camping, and emergency use where a versatile, easy to operate firearm is valuable. Production appears to have been limited, which makes surviving examples notable on the used market.

Pistols

Rexio pistols are the core of the brand. The Rexio Standard, marketed in the United States as the Super Comanche, is a single barrel break action pistol chambered in .410 with optional .45 Colt capability through barrel or muzzle adapters. A 250 mm barrel gives the gun an overall length of about 350 mm, with weight around 1.3 kg. Later compact models use 150 mm barrels for easier carry and handling. Operation is straightforward. The shooter presses a latch ahead of the trigger guard to tip the barrel open, loads a shell, cocks the external hammer, and fires. Opening the action again lifts the spent case for manual removal. Rexio also produced adjustable sight versions in .22 Magnum for export, plus the Rexio Super and Super 152 double barrel pistols that stack two .410 or .410 and .45 Colt barrels in an over under layout. These twin barrel “pistolones” present a large, intimidating muzzle profile and give users two quick shots from a compact package that resembles a large semi automatic pistol at first glance.

Combination And Survival Variants

Beyond basic .410 pistols, Rexio offered caliber and configuration options that added flexibility. Some Standard and Super models shipped with muzzle adapters and a disc shaped key that allowed owners to alternate between .410 shells and .45 Colt cartridges in the same gun. The Super series also spawned the Super 152, a short barrel double with aggressive styling, and at least one Model Super 250 M concept with a vertical foregrip. The fold stock survival gun represents the most versatile expression of the platform. With its .22 LR over .410 barrels, dual hammers, and compact folding metal stock, it takes the Rexio concept into the realm of camp and emergency firearms inspired by designs such as the M6 Air Crew Survival Weapon. Limited production makes these combination and survival variants interesting targets for collectors looking for an unusual South American take on multipurpose break action guns.
