Who It’s For
This revolver is built for the shooter who wants absolute reliability over magazine capacity. It’s ideal for CCW holders who prefer a revolver’s simplicity, home defenders who want a gun that works every time, and shooters who train with magnum loads and need a frame that won’t loosen over time. The 3″ barrel also makes it a solid backup for off-duty officers.

FAQ
Can I shoot .38 Special +P in the Ruger GP100 3″?
Yes. The GP100 is built to handle .357 Magnum pressures, so .38 Special +P is safe and actually reduces recoil for training. The cylinder is machined to accept both cartridges without issues.
Does the 3″ barrel affect accuracy compared to a 4″ version?
At typical self-defense distances (0–15 yards), accuracy is identical. The 3″ barrel is slightly less forgiving with heavy bullets, but for defensive loads (125–158 grain), you’ll see no practical difference.
Is the satin stainless finish easy to maintain?
Yes. The satin finish hides scratches better than polished stainless. Clean with a soft cloth and mild solvent; avoid abrasive pads. Per Ruger specs, the finish is corrosion-resistant for daily carry.
Will the Hogue Monogrip fit large hands?
Yes. The Monogrip fills the backstrap and has finger grooves that accommodate hand sizes from medium to XL. If you need a smaller grip, aftermarket options like VZ Grips are available.
Trust the Ruger GP100 3″ .357 Magnum Satin Stainless 6rd for your daily carry or nightstand. It’s the revolver that over 1 million GP100 owners have relied on since 1985 (Ruger sales data).
