Ruger GP100 Review: Ruger’s wheelgun workhorse!

Ruger GP100 Background
Ruger has established itself as one of the premier revolver manufacturers in the United States. Their offerings range from single action rimfires like the Bearcat and Single Six to magnum double actions like the Super Redhawk.
.357 models also feature prominently in the Ruger lineup. The Blackhawk and Vaquero models are among the most popular single action revolvers in the market. The SP101 is a great option for a concealed carry gun. And, finally, we have the GP100, Ruger’s full size double action .357.
The GP100 replaced the Security Six, Service Six, and Speed Six models. These predecessors had some success in the 1970s and 1980s in law enforcement and military service. Units like the Naval Investigative Service (precursor to the NCIS) and Postal Inspectors used various models in this range.
The GP100 is a modernized version of the Six series. It fills the same niche as the L-Frame Smith & Wesson revolvers, which are also designed for full-time .357 magnum use. Some smaller, lighter frames can accommodate the dimensions of the .357, but are not strong enough to handle the strain of thousands of rounds of magnum punishment. The solid steel frame of the GP100 lives for hot, full power ammo, and it is made for the shooter who would rather fire the real deal than .38 Special wadcutters.

Models and Variations of the Ruger GP100
Ruger has made a wide range of GP100 models. Most are chambered in .357, but versions in .22LR, .44 Special, .327 Federal, and 10mm are also available on a limited basis. Barrel lengths range from 2.5 inches to 6 inches. Various special models like the Match Champion have been made over the years. Some .357 models are also available with 7-shot cylinders in lieu of the traditional 6.
Ruger GP100 – Our Take
Recoil can be an issue on magnum revolvers. Unlike semiautomatics, which have a slide that moves against a recoil spring to slow down the felt recoil impulse, revolvers send all of the recoil force right into the shooter’s hand. The GP100 is much less abusive than the older breed of .357 wheelguns thanks to its grip design. Older revolvers generally had a grip frame with stocks attached to the sides. This placed the metal of the frame against the web of the hand, and metal does not give when pressed against flesh. The GP100 reshaped its frame so that rubber overmolded grips can fully surround the frame. This may not sound like much, but it makes a huge difference in the pain levels felt by the shooter.
The sights on the GP100 are good, with a traditional post-and-notch style in black. The rear sight is adjustable. This is beneficial for target shooters or people who like to stretch the .357’s legs out to the distances at which it is capable. They are a little less durable than fixed sights, though.
The GP100 is an accurate gun. Its fixed barrel, adjustable sights, and light single action trigger all work together. I found it easy to shoot groups at 25 yards in single action. The double action trigger pull is very smooth and also shot well.
My only real ergonomic complaint is the cylinder release button that Ruger uses on their revolvers. It is better than pulling to the rear as is done with a Colt, but not as nice as pushing forward on a Smith & Wesson. It is still plenty easy to use, and surely there are people who prefer this button to a sliding lever. But to me, it is faster and easier to push a release forward.
Reliability of revolvers tends to work a little differently than with semi autos. Because revolvers don’t rely on the energy produced through firing, bad ammo typically does not cause a failure to feed the next round. A dud round is addressed by simply pulling the trigger again. The GP100 is typical of other quality revolvers and will work when it is called upon.
Bad ammunition can cause a malfunction if a bullet jumps the crime of its case, but this is a fairly uncommon. This type of malfunction is theoretically less likely in a heavy gun than in a light gun, but in practice it is not really a factor. Buying quality ammo is the best way to avoid this issue.
If there is one word that describes the GP100’s construction, it is solid. It is readily apparent that this gun is made out of a large chunk of steel. Some revolvers feel like a collection of parts that are tacked together. Not so with the GP100. It lives to shoot full power .357 ammo all day, every day. If you do manage to wear something out, it is backed by one of the best service departments in the industry at Ruger.
Now, this robust construction does not come cheap. MSRP is around $1,000 for most models. MSRP is only a suggestion, and actual street prices vary wildly. However, directly comparable guns like the S&W 686 have list prices that are lower. Be sure to shop around before picking up a GP100. The GP100 has been in production for many years so the used market is worth checking too.
All in all, the GP100 is an excellent gun. It might not be a part of our best revolver rundown, but it is built to last decades and is a thoroughly enjoyable gun to spend time with. Should you happen to be in the market for a full-frame .357 Magnum, the GP100 is one you should consider.
