The DA/SA action allows the shooter to choose between double-action for fast first shots and single-action for precision. The fiber optic front sight and adjustable rear sight pair for quick target acquisition across different lighting conditions. The cushioned rubber grip with hardwood inserts absorbs recoil and maintains control during extended shooting. The transfer bar safety prevents discharge unless the trigger is fully pulled. ### Usage Notes The 4.2-inch barrel is a practical middle ground between the compact 2.5-inch and longer 6-inch configurations. It provides a longer sight radius and more velocity than the snub-nose variants without adding the overall length of the 6-inch barrel. At 40 oz. it is manageable for range use and home defense while being less suited to daily concealed carry than smaller alternatives. ## Frequently Asked Questions **Q: What caliber is the GP100?** A: The GP100 is chambered in .357 Magnum and also accepts .38 Special. **Q: Who makes the GP100?** A: The GP100 is made by Ruger. **Q: What type of firearm is the GP100?** A: It is a single/double-action revolver. **Q: What is the barrel length of the GP100?** A: This configuration has a 4.2-inch barrel. **Q: How many rounds does the GP100 hold?** A: It has a 7-round cylinder. **Q: What finish does the GP100 have?** A: The finish is satin stainless steel. **Q: What sights does the GP100 come with?** A: It has a fiber optic front sight and an adjustable rear sight. **Q: Where can I buy the GP100?** A: Compare current vendor offers on this page. ## What Reviewers Say *Quoted verbatim from YouTube reviews.

Build quality is the most consistent positive. The satin stainless finish holds up through heavy use and weather exposure, and the action runs smoothly across both .357 Magnum and .38 Special loads. Trigger feel in double and single action is described as predictable and comfortable for range work. Accuracy at standard defensive and target distances is consistently reported as strong. The 4.2-inch barrel gives enough sight radius for reliable performance at most practical distances. The versatility of running .357 Magnum and .38 Special is frequently mentioned as a practical advantage for both practice and defensive use. The revolver's weight and the 4.2-inch barrel keep it in a range where most owners use it for home defense and range shooting rather than everyday carry. Price comparisons with other revolvers land favorably for most buyers who weigh performance against cost. Some owners develop an attachment to the classic revolver format that the GP100 represents. ## Pricing **1 offers available** | Vendor | Price | |--------|-------| | Gunbuyer Com | $883.20 | ## Reviews **Average Rating:** 4.0/5 (1 reviews) > **toby_k** (4/5): I wanted this GP100 configured for smooth pocket carry, so I removed the sights and filed down the hammer.
