Frequently Asked Questions
Ruger GP 100 5 for sale
How much is a Ruger GP100 worth today?
Ruger GP100 revolvers typically cost around $919 today, with most listings ranging from $755 to $1,059. Prices vary based on barrel length, finish, and condition. New models in .357 Magnum remain in production and widely available through multiple retailers.
Is a Ruger GP100 worth it?
The GP100 is a well-built .357 Magnum revolver retailing around $700-900. It's known for durability, smooth trigger action, and handling full-power magnum loads without issue. For home defense, hunting, or range use, it competes favorably with pricier options. Most owners consider it worth the cost.
What are the common problems with the Ruger GP100?
GP100 owners report occasional issues: hammer pivot assemblies backing out during firing, cylinder chambers spaced too closely for some ammunition brands, and rare cylinder rotation failures. Most are minor and infrequent. Overall, the revolver remains durable and well-regarded for magnum shooting.
What hits harder, 357 or 45?
.357 Magnum hits harder. Most .357 loads produce around 500 ft.-lbs. of muzzle energy versus roughly 350 ft.-lbs. for standard .45 ACP. The .357's higher velocity also gives it better penetration, making it the stronger performer at typical handgun ranges.
What is the best barrel length for a 357 Magnum revolver?
Barrel length depends on intended use. For concealed carry or self-defense, 3 to 4 inches balances power and portability. For hunting or range shooting, 6 inches maximizes velocity and accuracy. Most shooters find 4 inches a practical all-around length for both performance and handling.
Will a 357 stop a grizzly bear?
A .357 Magnum is marginal for grizzly defense. Experts recommend larger calibers like .44 Magnum or 10mm for reliable stopping power. If forced to use a .357, load 200-grain hardcast bullets and aim for the brain or spine. Shot placement and penetration matter more than caliber alone.
Can you dry fire the Ruger GP100?
Yes, you can safely dry fire the GP100. Ruger's manual explicitly permits it, and the revolver's robust design handles repeated dry firing without damage. Many owners dry fire hundreds of times to smooth the action. Using snap caps is optional but recommended to reduce wear on the firing pin.
What is the shelf life of .357 Magnum ammo?
Properly stored .357 Magnum ammo remains reliable for 10+ years. Manufacturers typically rate shelf life at 10 years, though well-preserved rounds can function 25 years or longer. Storage conditions matter most—keep ammunition dry, cool, and away from moisture. For self-defense use, consider replacing every few years.
