The Ruger GP100 is a renowned dofble-action revolver that has gained widespread recognition for its durability, accuracy, and versatility. Since its introduction in 1985 by Sturm, Ruger & Co., the GP100 has been a preferred choice for law enforcement, self-defense, sport shooting, and hunting. Its solid steel frame, triple-locking cylinder, and rugged construction make it one of the most durable revolvers available.
This guide provides an in-depth look at the history, design, performance, variants, and practical applications of the Ruger GP100, offering valuable insights for enthusiasts, collectors, and potential buyers.
History and Development
The GP100 was developed as a successor to Ruger’s Security-Six series, incorporating significant design improvements to create a stronger, more user-friendly revolver. Ruger designed the GP100 to compete with revolvers like the Smith & Wesson 686 and Colt Python, offering similar performance with enhanced durability and affordability.
Introduced in 1985, the GP100 became an immediate success due to its heavy-duty frame, modular construction, and user-friendly features. It was designed to handle continuous use of full-power .357 Magnum loads, making it a reliable option for professionals and civilian shooters alike.
Design and Features
Frame and Build Quality
One of the defining characteristics of the GP100 is its solid stainless steel or blued alloy steel frame, which is engineered to withstand extreme stress and long-term use. Unlike many competitors that use side plates, the GP100 features a monolithic frame, which enhances strength and reduces potential failure points.
Barrel Length Options
The GP100 is available in multiple barrel lengths, including:
- 2.5 inches – Compact and ideal for concealed carry
- 3 inches – Balanced for self-defense and general use
- 4.2 inches – Versatile for home defense and target shooting
- 6 inches – Optimized for accuracy and hunting
- 6.5 inches – Extended performance for long-range shooting
Each barrel length offers different advantages depending on the shooter’s intended use.
Cylinder and Caliber Options
The GP100 is primarily chambered in .357 Magnum, which also allows it to shoot .38 Special rounds, offering flexibility in ammunition selection. Other caliber options include:
- .327 Federal Magnum – Lower recoil with respectable stopping power
- 10mm Auto – Higher velocity and stopping power for hunting or defense
- .44 Special – Classic revolver cartridge with moderate recoil
Trigger Mechanism
The GP100 features a double-action/single-action (DA/SA) trigger system, allowing shooters to fire in double-action mode (a long pull) or single-action mode (a shorter, lighter pull). The revolver’s smooth trigger pull and consistent break make it a favorite among precision shooters.
Grip and Ergonomics
One of the standout features of the GP100 is its cushioned rubber grip with optional wood inserts, designed to reduce recoil and improve comfort. The grip design helps distribute force evenly, making the revolver comfortable to shoot even with full-power .357 Magnum loads.
Sights
The GP100 is equipped with adjustable rear sights and ramp front sights, enhancing precision for both defensive and competitive shooting. Some models feature fiber optic or night sights for improved visibility in low-light conditions.
Performance and Shooting Experience
Accuracy
The heavy barrel and solid frame contribute to the GP100’s exceptional accuracy, making it a reliable choice for target shooting and competition. Many shooters report tight groupings at 25 to 50 yards, with the longer barrel versions offering even greater precision.
Recoil Management
Despite being chambered in powerful calibers, the GP100 manages recoil effectively due to its heavy build and ergonomic grip. The rubber grips with wood inserts provide superior control, making follow-up shots easier and more accurate.
Reliability
Ruger is known for producing some of the most reliable firearms on the market, and the GP100 is no exception. The triple-locking cylinder (locking at the front, rear, and bottom) ensures that the revolver stays in alignment and functions smoothly even after extensive use.
