Key Takeaways:
- Cabot builds closely fitted 1911 pistols using billet construction and precision machining.
- The South Paw reverses the ejection port and primary controls for left-handed operation.
- The functional Big Bang Set pairs right- and left-handed pistols made principally from Gibeon meteorite.
Cabot Guns introduced its 1911 pistols at the 2011 NRA Annual Meetings. The company worked with Penn United Technologies, a Pennsylvania manufacturer whose existing operations included precision tooling and components for aerospace, medical, and computer applications.[1]
That manufacturing background defined the early Cabot pistols. Frames and slides were cut from steel billet using waterjet, CNC, grinding, and electrical-discharge machining equipment. During a factory visit, American Handgunner writer Jeremy Clough tested multiple slides on randomly selected frames and found the components closely interchangeable. His testing also demonstrated that a replacement barrel could be installed without conventional gunsmith fitting.[1]
Cabot states that the raw steel, components, machining, assembly, and finishing used for its regular-production pistols originate in the United States. The company extends that claim to small components such as pins, springs, and grip-screw bushings.[2]
National Standard and Vintage Classic
The National Standard is Cabot’s core single-stack 1911. Its frame and slide are machined from 416 stainless-steel billet. Current configurations include a 5-inch Government model and a 4.25-inch Commander, each available in .45 ACP or 9 mm Luger. Standard features include a hand-fitted match-grade barrel, polished feed ramp, machined barrel bushing, full-length guide rod, lowered and flared ejection port, and checkering on the frontstrap and mainspring housing. Cabot guarantees groups smaller than 1.5 inches at 25 yards.[3]
The Vintage Classic uses the same chambering and size options, along with a 416 stainless-steel frame and slide. It differs primarily in presentation. Cabot applies a proprietary distressed finish and equips the pistol with traditional details such as walnut grips and an available gold-bead front sight. Despite its period appearance, it retains the company’s modern barrel, bushing, ejector, and sight construction.[4]
For identification purposes, collectors should record the model, serial number, chambering, barrel length, finish, grips, sights, safety arrangement, and factory-supplied accessories. Cabot offers enough optional features that two examples of the same model may differ materially.
National Standard South Paw
The National Standard South Paw is a mechanically reversed 1911 designed specifically for left-handed operation. Its ejection port is on the left side, while the slide stop, thumb safety, and magazine release are positioned for the left-handed shooter. The current model is chambered only in .45 ACP and is offered with either a 5-inch Government barrel or a 4.25-inch Commander barrel.[5]
Cabot’s earlier S103 Limited South Paw required reversed versions of the frame, slide, slide stop, thumb safety, grip safety, sear spring, magazine release, magazine, ejector, and extractor. American Rifleman confirmed that these components were manufactured specifically for the left-handed design rather than adapted from a standard right-handed pistol.[6]
The same publication tested the S103 from a Ransom Rest at 25 yards. When cleaned between five-shot groups, the pistol produced groups measuring between one-half and three-quarters of an inch. In conventional rested testing, with cleaning only between ammunition types, its average extreme spread was 2.33 inches. The review also reported that accumulated fouling affected accuracy and occasionally prevented the slide from locking open on an empty magazine.[6]
That test provides useful context for Cabot’s close-fitting construction. Mechanical precision can produce excellent accuracy, but it does not eliminate the need for appropriate lubrication and maintenance.
The Insurrection
Cabot moved beyond the traditional single-stack format with the Insurrection, introduced in 2023 as its first double-stack M1911-style pistol. The original configuration used a 5-inch barrel, 416 stainless-steel construction, 9 mm Luger chambering, a bilateral thumb safety, and a proprietary frame with an accessory rail.[7]
The Insurrection accepts STI/2011-pattern magazines and was supplied with two 17-round magazines at introduction. Its standard features included a full-length guide rod, fiber-optic front sight, ledge-style rear sight, and diamond-like carbon finish. An optic mounting system and barrel ports were offered as options.[7]
The model represents a clear division in Cabot’s production history. Earlier pistols applied the company’s machining methods to the conventional single-stack 1911. The Insurrection added a double-stack frame and increased magazine capacity while retaining billet construction and Cabot’s stated 1.5-inch accuracy guarantee.[7]
Damascus-Steel Pistols
Cabot also manufactures pistols using modern pattern-welded steel. This material is produced by forge-welding different steels into a billet and manipulating the layers through cutting, folding, twisting, or restacking. Etching the finished component exposes the resulting pattern.[8]
Cabot distinguishes between standardized stainless Damascus, which can be produced with relatively repeatable properties, and smaller batches intended for limited or individually commissioned pistols. Because the visible pattern derives from the individual billet, photographs of a pistol’s frame and slide can assist in confirming the identity of a documented Damascus example.[8]
The Big Bang Pistol Set
Cabot’s best-known commission is the Big Bang Pistol Set, a matched pair of functional 1911s made principally from a 77-pound section of the Gibeon meteorite. The pair consists of one right-handed pistol and one mechanically reversed left-handed pistol.[9]
Before machining, the meteorite section was examined by X-ray and three-dimensional laser scanning. Cabot then used computer modeling, electrical-discharge machining, and electron-beam technology during construction. The frames, slides, triggers, barrel bushings, and numerous other parts were made from meteorite material. Steel was retained for components including the barrels, springs, sears, pins, screws, hammer struts, and selected reinforced surfaces.[9][10]
Cabot test-fired both pistols before presenting the completed set at the 2016 NRA Annual Meetings in Louisville, Kentucky. The polished and acid-etched surfaces reveal the meteorite’s internal crystalline structure, while portions of its natural exterior remain visible on selected components.[9][10]
The Big Bang Set brought together two established Cabot programs: the company’s work with unconventional materials and the reverse engineering developed for its left-handed 1911s. Unlike a presentation pair containing two conventionally configured pistols, its mechanical arrangement is genuinely mirrored.
