The Ruger GP100 has been in production for twenty-five years now, replacing the dandy Security-Six/Speed-Six/Service-Six line of double-action revolvers. Replacing the Six series, it had big shoes to fill, but has proven a worthy replacement, stronger than its predecessor. The GP100 is about as rugged and reliable as you can get in a 357 Magnum double-action revolver. The GP100 is a gun that you can buy and shoot all you want. Full-house 357 Magnum loads can be used with no limitation on the number of rounds that you can feed through the sixgun. With the GP, you do not have to worry about cracking the forcing cone, or the revolver getting out of time. Just shoot it, then shoot it some more. The GP100 has a solid frame design, meaning that there is no side plate. The internals are removed through the bottom, with most connected to the trigger guard. These are tough, reliable revolvers, balance well, and are compact enough to serve as a duty gun, and also for concealed carry, properly holstered.

The latest in the GP100 line is the Wiley Clapp GP100. Wiley Clapp is a gun writer who has been at his craft for many years, and worked with Robert Coyle of TALO, Inc. on the features and specifications of this particular version of the GP100. Most noticeable is the good-looking matte stainless finish, and the handsome checkered wood grip inserts that are inset into the one-piece synthetic rubber grip. The GP100 grip is very comfortable when shooting heavy magnum loads, and the design of the grip panels puts the checkering on the portion of the grip that is just underneath the shooter’s fingers. The sights are different than on other variations of the GP100. The rear is a rugged Novak unit that is adjustable for windage correction, and the front blade has a green fiber optic rod, for better use in low lighting conditions, while still retaining the squared profile preferred by most target shooters. This GP100, while it would serve as a hunting tool, is built for defense, and it is well-suited to the task.

The 357 Magnum has been proven on the streets and in the back alleys for decades. The cartridge has a very good reputation for bringing a fight to an end. The 125 grain jacketed hollowpoint is my favorite bullet for social work in the 357 Magnum, and this special version of the GP100 is a very good platform from which to launch that bullet. Many folks these days think that one must have a high capacity magazine holding a score of cartridges, but the fact is that most handgun fights are over within the span of a couple of seconds, with few shots fired. The 357 Magnum is as good as it ever was as a fight stopper, and a good, reliable revolver makes for an effective weapon in a gunfight. Another advantage of a revolver that is seldom mentioned out of political correctness, is that the revolver does not leave the empty cartridge cases lying on the ground as does an autoloader. Even in a justified self-defensive shooting, there are some jurisdictions in which a person will be prosecuted by the law for using a firearm in defense of his life. In such a situation, you do not want to leave cartridge cases on the ground that have your finger prints upon them. A semi-auto flings its empty brass upon the ground. The GP100 does not. Usually this is not a concern, but there are some areas in which, even if morally justified to do so, using a handgun to defend yourself or someone else will get you time in prison. It ain’t right, but that’s the way it is. In such areas, you do not want to leave evidence at the scene of even a justified shooting. Anyway, if you choose to carry a revolver for whatever reason, the GP100 is a fine choice, and the three-inch barrel of this GP is a good balance of portability and power. The Novak rear sight, combined with the fiber-optic front is a good sighting combo for defense, and a Crimson Trace Lasergrip is easy to add, if desired.

Like any modern double-action revolver, the GP100 is easy to use, easy to load, and easy to maintain. The GP100 can be fired with a long pull of the trigger (double-action) or by first thumb-cocking the hammer for a light, crisp trigger pull (single-action) In a gunfight, double-action is best. The weapon is drawn from the holster, aimed, and the trigger is pulled. No safeties to manipulate at all. Just point and shoot. When finished, place the weapon back into the holster. The manual-of-arms is very simple with a double-action revolver, and it is easy to determine whether or not the weapon is loaded, even by a novice shooter.
