Everything You Need to Know When Buying a Ruger GP100 in America Online

The Ruger GP100 has come up repeatedly throughout discussions of the Colt Python, the Ruger Redhawk, and Ruger’s broader revolver lineup — and for good reason. Introduced in 1985, the GP100 is widely regarded as one of the best all-around .357 Magnum double-action revolvers ever made: rugged enough to fire an essentially unlimited diet of full-power magnum ammunition, comfortable enough to shoot all day, and affordable enough to be a genuine workhorse rather than a safe-queen. This guide covers where it came from, the engineering that makes it distinctive, full specifications, and what to know before buying one. Ruger GP100 For Sale USA

What the GP100 Replaced: The Security-Six Story

To understand the GP100, you have to understand the gun it replaced. Ruger’s Security-Six (along with its variants, the round-butt, fixed-sight Speed-Six and the fixed-sight duty-oriented Police Service-Six) launched in 1972, designed by Harry Sefried — who had previously designed the High Standard Sentinel revolver and reused that gun’s grip profile on the Six line. The Security-Six was genuinely innovative for its era: it used a one-piece frame rather than a removable side plate, giving it superior strength compared to many competing designs. It proved itself quickly, earning widespread law enforcement adoption throughout the 1970s and competing directly with entrenched Smith & Wesson and Colt duty revolvers. Approximately 1.24 to 1.5 million Security-Six family revolvers were produce between 1972 and 1988.

But by the early 1980s, Ruger’s engineers wanted something stronger — a platform that could handle an unlimited volume of full-power .357 Magnum ammunition without the frame-stretching wear concerns that affected lighter-framed designs (including the Security-Six itself) over tens of thousands of rounds. That project became the GP100, introduced in 1985–1986 specifically to replace the Security-/Speed-/Service-Six line entirely. Production of the Security-Six wound down accordingly, with the last examples shipped in 1988, closing a sixteen-year chapter as the GP100 took over its role in Ruger’s lineup — including in the same hunting, target-shooting, and duty markets the Six-series had served.

The Engineering That Sets the GP100 Apart

The GP100 is often describe as the first of a second generation of Ruger double-action revolvers, and it earn that distinction through several genuine engineering advances, some borrowed and refined from the Redhawk (introduce a few years earlier) and some entirely new:

Separate Hammer and Trigger Springs

The GP100 was design with separate springs for the hammer and trigger — a departure from designs using a single spring for both functions, and conceptually similar to an approach being develop around the same period in Britain for the Sterling revolver. This separation allows for a notably smoother trigger action than a share-spring design typically produces. Ruger GP100 For Sale USA

Triple-Locking Cylinder (Borrowed from the Redhawk)

The GP100 adopted the crane-mounted locking lever mechanism the Redhawk had introduced a few years earlier, rather than relying on the end of the ejector rod for cylinder lockup — a meaningfully stronger approach that became a defining feature across Ruger’s modern double-action revolvers.

Full-Length, Heavy-Duty Frame

The GP100 was build with a beefier frame and full underlug barrel than the Security-Six, using stronger steels and a redesign grip frame, and — notably — maintaining consistent frame thickness across all calibers, regardless of which specific chambering a giving GP100 was build in.

The Peg Grip System: A Genuinely Clever Solution

This is one of the GP100’s most distinctive and practically useful design features. Traditional revolver frames have exposed metal at the front and rear of the grip area, with the frame itself dictating the grip’s shape — meaning a manufacturer wanting to offer both a round-butt (concealment-oriented) and square-butt (target-oriented) version of the same gun traditionally needed two different frame shapes entirely. The GP100 solve this with a small rectangular peg grip frame, just large enough to enclose the hammer spring and strut, onto which a wide variety of different grip styles and shapes can be fitting — round-butt, square-butt, target, or compact — all using the same underlying frame. This is a major reason the GP100 has been offer with such a wide range of available grip configurations over its production history, more than most competing revolver platforms.

Was It Really Designed for Unlimited .357 Magnum Use?

This claim shows up consistently across historical sources on the GP100, and it’s worth explaining what it actually means rather than treating it as pure marketing language. Full-power .357 Magnum ammunition generates enough pressure and stress that many lighter-framed revolvers — including, over time, the Security-Six the GP100 replaced — can experience frame stretching or accelerated wear after a very high volume of rounds fired. The GP100’s combination of a heavier, full-length frame, the triple-locking cylinder mechanism, and stronger steels was specifically engineer to eliminate that concern, allowing the gun to handle a genuinely unlimiting diet of full-power .357 Magnum ammunition over its service life without the long-term durability concerns that affecting earlier, lighter designs. This is a real, documenting engineering goal behind the GP100’s design, not just a slogan. Ruger GP100 Price in UA

GP100 vs. Redhawk: Two Ruger Double-Actions, Different Purposes

Since both guns share DNA (the GP100 borrow the Redhawk’s crane-lock mechanism) and both are cover in this series, it’s worth clarifying how they differ:

Feature	GP100	Redhawk
Primary Caliber Focus	.357 Magnum (also .327 Fed. Mag., 10mm, .44 Special, .22 LR variants)	.44 Magnum (also .357 Magnum, .45 ACP/.45 Colt)
Frame Size	More moderate	Larger, heavier-duty
Weight	35–45 oz	~49 oz
Positioning	Versatile all-rounder, widely regarded as one of the best general-purpose .357 Magnum revolvers made	Heavy-duty, magnum-focused workhorse
Grip System	Interchangeable “peg” grip frame	Traditional Redhawk grip (round-butt option on some chamberings)

Bottom line: the GP100 is generally the better choice for shooters who want an excellent, moderately-sized .357 Magnum revolver for regular use; the Redhawk in .357 Magnum (or, more commonly, .44 Magnum) serves buyers who specifically want maximum frame mass and durability margin, at the cost of size and weight.

Real-World Reputation: Ruger GP100 For Sale USA

The GP100 has built a reputation, sustained across four decades, as one of the most comfortable double-action revolvers to shoot in its class — American Rifleman has specifically described GP100s as remaining one of the most comfortable revolvers to shoot, a reputation tied directly to the frame mass and grip design working together to tame full-power .357 Magnum recoil. It’s also consistently cited as a strong value: rugged, reliable, and genuinely affordable relative to comparable revolvers from other major manufacturers, which is a significant part of why it’s remained a staple of Ruger’s lineup since 1985 and has sold over 734,500 units.

The GP100 has also been the subject of distributor-exclusive special editions over the years — for example, a Wiley Clapp/TALO GP100 configuration (3″ barrel, 37 oz, 6-round capacity, MSRP around $829 at the time of its American Rifleman review) — reflecting the platform’s popularity as a base for both standard-catalog and specialty configurations.

Who Should Buy a Ruger GP100?

Shooters who want a genuinely all-purpose .357 Magnum double-action — hunting, target shooting, home defense, and range use are all well serve by the GP100’s combination of durability, accuracy, and manageable recoil.

High-volume shooters and handloaders who specifically want a revolver engineer to handle sustain full-power .357 Magnum use without long-term wear concerns.

Buyers who want grip customization flexibility — the peg grip system allows switching between round-butt, square-butt, and other grip styles on the same underlying frame, a genuine practical advantage over revolvers where grip shape is fixe by the frame itself. Ruger GP100 Delivery in USA

Consumers considering less common GP100 chamberings — the .327 Federal Magnum, 10mm Auto, .44 Special, and .22 LR variants each serve specific niches (higher capacity, semi-auto-cartridge revolver shooting, milder big-bore practice, and low-cost training, respectively) worth considering depending on individual priorities.

Buyers who specifically want maximum frame mass for .44 Magnum-level power should look at the Redhawk instead, since the GP100 doesn’t offer a .44 Magnum chambering.

Frequently Asked Questions by Americans

What did the GP100 replace in Ruger’s lineup?

The Security-Six, Speed-Six, and Police Service-Six line, which Ruger produced from 1972 to 1988.

Why is the GP100 considered so durable for .357 Magnum use?

It was specifically engineered with a heavier full-length frame, a triple-locking cylinder mechanism borrowed and adapted from the Redhawk, and stronger steels, aimed at handling an unlimited volume of full-power .357 Magnum ammunition without the frame-stretching wear concerns that affected lighter designs like the Security-Six.

What’s the peg grip system?

A small rectangular grip frame just large enough to enclose the hammer spring and strut, allowing a wide range of different grip shapes (round-butt, square-butt, target, compact) to be fitted to the same underlying frame — something most traditional revolver designs can’t offer without using entirely different frame shapes.

What calibers is the GP100 available in?

Primarily .357 Magnum/.38 Special (6 or 7-shot cylinder), with additional variants in .327 Federal Magnum (7-shot), 10mm Auto (6-shot), .44 Special (5-shot), and .22 Long Rifle (10-shot).

How does the GP100 compare to the Redhawk?

The GP100 is more moderately sized and specifically optimized around .357 Magnum as a versatile all-rounder; the Redhawk is larger, heavier, and most closely associated with .44 Magnum, offering greater frame mass at the cost of size and portability.

How many GP100s has Ruger made?

Approximately 734,500 units since the line’s 1985 introduction.

What barrel lengths and finishes are available?

Barrel lengths range from 2.5″ to 6″, in full-lug or half-lug profiles, with blued carbon steel or polished stainless steel finish options depending on the specific model.

Ruger GP100 Maintenance Tips: Ruger GP100 For Sale USA

• Clean after every range session, with particular attention to the forcing cone and each individual cylinder chamber.
• Use .38 Special for lower-recoil practice in .357 Magnum-chambered models — cheaper and gentler on both shooter and gun than full-power .357 Magnum.
• Take advantage of the interchangeable grip system to find the shape and size that fits your hand and intended use best, rather than assuming the factory-standard grip is the only option.
• Store properly, with a light coat of gun oil on exposed metal surfaces and dry, secure storage to protect either the blued or stainless finish.
• Leave anything beyond routine cleaning and basic maintenance to a qualified gunsmith, particularly work involving the triple-locking cylinder mechanism or internal lockwork.

Conclusion

Lastly, the GP100 is the gun this entire Ruger chapter has been building toward, and it earns that position honestly. It didn’t emerge from nowhere — it replaced a genuinely good revolver (the Security-Six) because Ruger’s engineers wanted something that could absorb a truly unlimited diet of full-power .357 Magnum without the frame stretching that even a solid, well-regarded design like the Security-Six could eventually show. The result borrowed the Redhawk’s triple-locking cylinder, added separated hammer and trigger springs for a smoother pull, and then solved a problem almost nobody else had bothered to solve cleanly: letting one frame accept round-butt, square-butt, or target grips without needing different frame geometry for each.
