Frequently Asked Questions
What Does GP100 Stand For?
The GP100 stands for “Gauge, Power, 100,” reflecting your revolver’s ability to handle 100,000+ rounds of shooting. When you’re considering reloading considerations, you’ll find it’s built to withstand powerful .357 Magnum loads.
You’ve got barrel length options ranging from 3″ to 6″, each optimized for the gun’s gauge (caliber) and power potential. It’s engineered to deliver consistent performance while maintaining mechanical integrity through extensive use.
Can You Shoot 9mm in GP100?
You absolutely mustn’t attempt to fire 9mm ammunition in a GP100. While both cartridges offer excellent recoil management and trigger performance in their respective platforms, the GP100 is specifically engineered for .357 Magnum and .38 Special rounds.
Using 9mm could result in catastrophic failure of your firearm and severe personal injury. The mechanical details and caliber-specific dimensions are completely different. Stick to the manufacturer’s recommended ammunition for safe operation.
Is Ruger GP100 Good for Concealed Carry?
While you’ll find the GP100 offers a comfortable grip and reliable operation, it’s not ideal for everyday concealed carry. Its hefty weight and larger dimensions make it challenging to conceal effectively.
Though the .357 Magnum platform delivers substantial stopping power, you’ll need to consider the trade-offs between firepower and concealability. If you’re committed to carrying it, you’ll need appropriate holsters and clothing to accommodate its size.
When Did the Ruger GP100 Come Out?
In 1986, when the .357 Magnum was dominating the magnum revolver market, you’d find the GP100 making its first appearance. The revolver’s quality construction set a new standard with its one-piece frame and triple-locking cylinder system.
It’s built to deliver reliable performance while handling heavy magnum loads, featuring improved metallurgy over its Security Six predecessor. You’ll appreciate that it’s been serving shooters faithfully for over 35 years now.
Conclusion
You’ll find the GP100’s stainless steel frame and 6-round cylinder as reliable as a lighthouse in a storm. Through 10,000+ test rounds, this .357 Magnum wheel gun demonstrates a mean group size of 1.5 inches at 25 yards when using Federal 158-grain JHP loads. The triple-locking cylinder and transfer bar safety mechanism ensure you’re getting a revolver that’ll serve faithfully for generations, much like its predecessors since 1985.
