When you’re looking at a Ruger GP100 357 Magnum stainless revolver with a 4-inch barrel, you’re considering a firearm known for its durability and ability to handle full-power .357 Magnum loads. This isn’t a delicate range toy; it’s built to last, which is why it’s been a popular choice for decades among those who need a tough, reliable revolver.
What are the key features of the Ruger GP100?
- Stainless Steel Construction: The entire revolver, including the frame, barrel, and cylinder, is made from stainless steel. This provides excellent corrosion resistance and makes the firearm very robust, capable of handling thousands of rounds of .357 Magnum. It’s a practical choice for Kansas weather, whether you’re out hunting or just at the range.
- Triple-Locking Cylinder: Ruger’s design locks the cylinder into the frame at the front, rear, and bottom. This ensures precise alignment and contributes to the GP100’s reputation for strength and accuracy. It’s a feature you can feel when you handle it – solid as a rock.
- Recoil-Reducing Grip: The GP100 comes with a comfortable, cushioned rubber grip with hardwood inserts. This design helps absorb recoil, making even stout .357 Magnum loads more manageable, especially during extended shooting sessions. It’s a thoughtful touch that makes a real difference.
- Adjustable Sights: Equipped with a ramp front sight and an adjustable rear sight, you can fine-tune your point of impact for different loads or shooting distances. This is important for a revolver that might be used for anything from target practice to hunting small game.
- Easy Takedown: The GP100 is designed for straightforward disassembly without special tools, which simplifies cleaning and maintenance. As anyone who’s spent time at the range knows, a gun that’s easy to clean is a gun that gets cleaned more often.
- Chambered in .357 Magnum: This allows for the use of both powerful .357 Magnum ammunition and the milder, more affordable .38 Special and .38 Special +P rounds. This versatility is a big plus, letting you tailor your ammo to your activity, whether it’s target shooting or self-defense.
Who should consider the Ruger GP100 357 Magnum Stainless Revolver with 4-Inch?
Buy it if:
- ✅ You’re looking for a robust, reliable revolver that can handle heavy use and full-power .357 Magnum loads.
- ✅ You want a versatile handgun for home defense, target shooting, or even as a backup for hunting.
- ✅ You appreciate the durability and corrosion resistance of stainless steel firearms.
- ✅ You prefer a revolver with a comfortable, recoil-absorbing grip for better shootability.
- ✅ You need a firearm that is relatively easy to disassemble and maintain.
- ✅ You value a firearm known for its strong construction and longevity, a true workhorse.
Skip it if:
- ❌ You’re looking for the lightest possible handgun for concealed carry. While a 4-inch GP100 can be carried, its weight (40 oz) might be more than some prefer for daily concealed carry. See our Concealed Carry options for lighter alternatives.
- ❌ You primarily shoot .22LR and don’t need the power or recoil of a .357 Magnum.
- ❌ You prefer a semi-automatic pistol for higher capacity and faster reloads.
What are the pros and cons of the Ruger GP100 357 Magnum Stainless Revolver with 4-Inch?
Pros:
- ✅ Exceptional Durability: The stainless steel construction and triple-locking cylinder make this one of the toughest revolvers on the market, built to withstand a lifetime of use.
- ✅ Versatile Ammunition Use: Shoots both .357 Magnum and .38 Special, offering flexibility for different applications and budgets.
- ✅ Recoil Management: The heavy frame and excellent rubber grip significantly reduce felt recoil, making it more comfortable to shoot, even with hot loads.
- ✅ Accuracy: The solid construction and adjustable sights contribute to good accuracy, whether at the range or in the field. Many a Kansas deer has been taken with a .357, and this Ruger GP100 4 inch barrel 357 review often highlights its precision.
- ✅ Easy Maintenance: Simple takedown design means you can keep it clean without a fuss.
Cons:
- ❌ Weight: At 40 ounces, it’s a heavy revolver. This is a pro for recoil absorption but can be a con for prolonged carrying, especially if you’re hiking all day during pheasant season.
- ❌ Bulk: The robust frame, while strong, makes it less ideal for deep concealment compared to smaller, lighter options.
- ❌ Capacity: Like most revolvers, it’s limited to 6 rounds. If you need higher capacity, you might want to look at our Semi-Automatic Pistols.

The Ruger GP100 sits comfortably in the middle ground between budget-friendly options like the Taurus 605 and premium revolvers such as the Smith & Wesson 686. While the Taurus might be appealing for its lower price point, it generally doesn’t offer the same level of robustness or refinement as the GP100, especially when you’re talking about sustained use of .357 Magnum. The S&W 686 is a fantastic revolver, often praised for its smooth trigger and fit and finish, but it comes at a significantly higher price. The Ruger GP100 357 Magnum 6 inch review often points out similar strengths to the 4-inch model, primarily its tank-like build. For many, the Ruger GP100 represents the best balance of strength, reliability, and value for a full-sized .357 Magnum revolver.
