The Ruger GP100 in .357 Magnum is a double-action revolver with a 5-inch blued steel barrel and a 6-round capacity. The transfer bar safety prevents the hammer from reaching the firing pin unless the trigger is fully pulled, making it safe to carry with all chambers loaded. Finger-grooved rubber grips reduce felt recoil during sustained .357 Magnum firing and improve control compared to smooth wood grips.

Detailed Features 

The double-action mechanism fires with either a long trigger pull (double action, hammer uncocked) or a light pull after manually cocking the hammer (single action). At 5 inches, the barrel provides a longer sight radius than compact revolvers, which helps with accuracy at target shooting distances, while staying shorter than 6-inch target models. 
 
Adjustable front and rear sights allow windage and elevation corrections for different loads and distances. The GP100 frame is built heavier than most revolvers at this price point, which contributes to its reputation for handling full-power .357 Magnum loads reliably over many thousands of rounds. The blued finish requires more maintenance to prevent rust than stainless variants but gives the revolver a classic look. 
 

Usage Scenarios 

At the range the 5-inch barrel and adjustable sights suit deliberate target practice, and the double-action pull works for timed drills. For home defense, the reliable double-action mechanism and .357 Magnum stopping power are practical assets. The GP100 also sees use as a trail gun for hikers and campers who want significant stopping power in a revolver format.

The GP100 in .357 Magnum with the 5-inch barrel has a strong reputation among revolver owners. Build quality is the most consistently praised attribute. Ruger's GP100 frame is heavier and more overbuilt than comparable revolvers, and owners describe it as handling full-power .357 loads without any sign of wear after high round counts. The double-action trigger pull is smooth by factory revolver standards and improves with use.

The rubber grips are appreciated for reducing felt recoil, particularly during extended .357 Magnum sessions. The adjustable sights are a practical advantage over fixed-sight revolvers for shooters who vary their ammunition.

Critiques focus on weight. The GP100 is heavier than average for a service revolver, which makes it less ideal for concealed carry. Some buyers who prefer semi-automatics note the 6-round capacity as a trade-off versus double-stack pistols. Overall, the GP100 is regularly cited as one of the most durable factory revolvers available in its price range.
