Compare Armscor products

Armscor is a Philippine firearms and ammunition maker, headquartered in Marikina and best known in the US through its Rock Island Armory (RIA) brand of 1911 pistols. The company is one of the largest gun manufacturers in Southeast Asia and has built its US reputation on value: affordable, GI-pattern and competition-ready 1911 and 2011-style pistols, backed by an in-house ammunition line. For American shooters, Armscor is the name behind some of the lowest-priced ways into the 1911 platform, plus a steady supply of brass-cased range ammo. Its US operation, Armscor International, is based in Pahrump, Nevada, with an ammunition plant in Stevensville, Montana.

History & background

Armscor's roots in the Philippines run back to the 1950s, and the company has been building on the 1911 design for decades — a long production history that underpins its manufacturing routine and its ability to hold competitive prices. Rock Island Armory, the brand under which most of its handguns reach the US, was brought under Armscor in the 1980s.

The company runs a genuinely transnational operation. Pistols are manufactured in the Philippines, while Armscor International handles US distribution from Nevada and, since 2011, produces ammunition at a facility in Stevensville, Montana. That dual footprint — Philippine firearms manufacturing plus US-based ammunition production and distribution — is central to how the brand competes in the American market.

What they're known for

1911 pistols (Rock Island Armory). This is Armscor's signature. The lineup runs from bare-bones GI-pattern guns — among the most affordable new 1911s on the US market — up through feature-loaded competition models. Frames and slides are built from 4140 ordnance steel, typically with a parkerized finish, the same rugged, no-nonsense construction the platform is known for. Calibers include 9mm Luger, .45 ACP and 10mm Auto, and because the guns follow the standardized 1911 pattern, the global aftermarket of parts and upgrades is wide open to owners who want to tune them.

2011-style high-capacity pistols. Armscor's double-stack models (such as the TAC Ultra family) move from the classic single-stack 1911 to a wider, higher-capacity 2011-pattern frame — 17 rounds in 9mm — aimed squarely at practical/USPSA-style competition. They ship with competition features like adjustable sights, fiber-optic front sights, a magazine well and multiple magazines at a price well under premium 2011 brands.

STK100. A departure from the 1911 lineage, the STK100 is a striker-fired 9mm with a 7075-T6 aluminum frame and a 1911-like grip angle. Its standout practical feature is compatibility with Glock 17 magazines, which keeps spare-magazine costs low.

Ammunition. Armscor is also a high-volume ammunition maker, producing brass-cased range and training loads in the common US calibers — 9mm, .45 ACP, .38 Special, .357 Magnum, .223/5.56 and others — plus .22 LR rimfire. It is the sole source of factory ammunition for the proprietary .22 TCM, a high-velocity bottlenecked cartridge it developed for its 1911 platform.

Buying guide — which Armscor is right for you

First 1911 / club gun: The GI-pattern Rock Island 1911 in 9mm or .45 ACP is the entry point — purist, low-maintenance and inexpensive. In 9mm the running costs stay modest, and the standard 1911 pattern means you can upgrade later. One thing to weigh: if you know you want sights, a mag well and a fiber-optic front, it can be cheaper to buy a better-equipped model up front than to add those parts piecemeal.

Practical/USPSA competition: The double-stack 2011-style TAC Ultra in 9mm is the value pick for the divisions that allow it — high capacity, competition sights and a mag well out of the box, often with several magazines included. Note the wider grip: shooters with smaller hands should handle one first, or stay with a slimmer single-stack model.

Range and target shooting: Longer-barreled "match"-style 1911s with 6-inch barrels give a longer sight radius for shooters focused on accuracy from the bench or static stages.

Striker-fired shooters: The STK100 is the pick if you prefer a modern striker-fired pistol but want the Glock-magazine compatibility and Armscor pricing.

Ammunition: Armscor brass-cased FMJ is a straightforward value choice for feeding any of the above in 9mm, .45 ACP or .223/5.56. If you run a .22 TCM 1911, Armscor is your factory-ammo source.

A practical caution echoed by reviewers: these are value guns, and the factory trigger is functional rather than refined. The upside of the standardized 1911 platform is that a trigger or sight upgrade is easy and inexpensive when you want to take it further.

Reputation & reviews

In the US, Armscor and Rock Island Armory are widely regarded as the value benchmark in 1911s — guns that deliver the platform's feel and reliability at a fraction of premium-brand prices. Reviewers consistently frame them as a lot of gun for the money, with honest caveats: triggers and fit aren't at the level of high-end makers like Staccato or Wilson Combat, which cost several times as much. The double-stack TAC Ultra in particular has been praised as competition-ready out of the box for its price, with the main reservation being grip width. On the ammunition side, Armscor's range loads are treated as serviceable, economical practice ammo.

Armscor on US-GUNDEALS

Armscor spans two categories on US-GUNDEALS — handguns and ammunition — and sits in the value tier in both. On the firearms side that means 1911s and 2011-style pistols from entry-level GI models up through competition guns; on the ammunition side, brass-cased range loads in the common calibers. Pricing moves with model, configuration and availability, so comparison is worthwhile. The price comparison shows current Armscor and Rock Island Armory offers from across the shops in one place, so you can quickly find your model or load in stock at the best price.
