About This Firearm
The Ruger GP100 is a stainless double-action .357 Magnum built for range work and woods carry. It has an MSRP of $1,109. Its cylinder locks into the frame at the front, the rear and the bottom, which keeps chamber and bore in line under full-power loads.
It arrives sighted and adjustable. The rear sight adjusts, the front is a ramp, and a given bullet weight can be zeroed. A Hogue Monogrip is fitted over the grip peg with no metal left bare at the backstrap, so magnum recoil lands on rubber. A transfer bar blocks the firing pin until the trigger is all the way back, and no manual safety is fitted. The barrel is 4.2 inches with a full underlug, the gun is 9.5 inches overall, and nothing on it takes an optic.
If you're cross-shopping, the Smith & Wesson Model 686 Plus has an MSRP of $1,039, weighs 39.2 oz against this gun's 40 oz, and fits a seventh round into a cylinder of the same class. The Ruger SP101 covers the same cartridge for carry at 26 oz behind a 2.25-inch barrel with an MSRP of $939, and holds five.

Strengths & Limitations
- Ruger builds the subassemblies to come apart without special tools, so cleaning past the bore does not mean a trip to a shop.
- The grip is a rubber sleeve over the peg, so changing it is a cheap way to change how the gun feels.
- There is no key, no lock and no lever on the frame, so there is one fewer part to fail.
- Six rounds in a frame this size, where a Smith & Wesson Model 686 Plus holds seven for a lower MSRP.
- No optic provision of any kind, so a dot on this gun means a machine shop and a refinish.

Frequently Asked Questions
Does it have a safety lever?
No. A transfer bar carries the hammer blow to the firing pin, and it rises into place behind the pin as the trigger is held fully to the rear.
Can it shoot .38 Special?
Yes, as any .357 Magnum chamber can. .38 Special is the milder practice load in it.
What is the twist rate?
A 1:18.75 right-hand twist, cut with five grooves.
Will aftermarket grips fit?
Yes. Ruger states the grip frame accommodates a wide variety of custom grips, and the factory Monogrip is a single piece that pulls off the peg.
