The 9MM COMMANDER 4.25″ DOUBLE STACK has a match-grade, stainless-steel, 4.25-inch barrel with a reverse muzzle crown. The outside of the chamber is fluted to provide places for powder residue and crud to go so that they donÕt build up in areas that could slow down the slide’s cycling.

The barrel uses a traditional bushing, and the pistol comes with a polymer bushing wrench. (It also comes with a small Allen wrench, a Torx wrench, a button-shaped backstrap takedown tool, and a very nice soft gun rug with two zippered outside pockets on one side and seven magazine-size pockets that are covered by a Velcro flap on the other.) Also, the barrel has an integral feedramp and a fully supported chamber. The pistol has a standard Commander-length recoil spring guide assembly.

The slide has wide, square-bottom grasping grooves up front and at the rear. The rear of the slide has fine horizontal striations to the tune of 40 lines per inch. The top of the slide also has fine striations between the front of the rear sight and the back of the front sight, and they are done 30 lines per inch.

The front of the slide is machined with a relief cut that is reminiscent of the Browning Hi Power pistol. It is designed to make one-handed holstering smoother. And the bottom edges of the slide are given a heavy chamfer to remove a potentially sharp edge that might cause wear on your holster, clothing, or hands.


The pistol comes with WilsonÕs all-black Battlesight rear sight that has a 0.145-inch-wide U-shaped notch. The face is horizontally striated, and the sight is both dovetailed into and screwed onto the slide with two screws. The front sight has a red fiber-optic rod, and it mates up perfectly with the U-shaped rear sight notch. The front sight housing is 0.128-inch thick and 0.198-inch tall (as best as I can measure them). The sight radius is 5.95 inches.

The Experior Commander Double Stack also features a Wilson Combat Concealment Bullet Proof hammer, a Bullet Proof magazine release, and a Bullet Proof thumb safety. The slide stop is countersunk on the offside.
