When Guns.com asked me to review the SIG P320 AXG Classic, I thought, “Oh, another ‘Wonder 9’ competing for the shooting public’s attention." 

Upon opening the box, I thought, “Wrong again, Ronbo.”

This gun is impressive! It is a smaller version of its military-issue cousin, the full-sized M17 that SIG first produced for the 101st Airborne.

SIG Sauer P320 AXG Classic 9mm Pistol

Viewing the P320, my eyes are drawn to the red-colored walnut grips. They contrast against the blue metal slide and frame. These grips are nicely checked and cover the rear grip strap as well as the side plates. This is unusual when compared to a Colt 1911-style pistol. 

Notice that the P320 has few controls. No thumb safety nor grip safety to get in the way of a fast first shot when you need it. The trigger is a metal, no-nonsense revolver-style that breaks crisply at 5.5 pounds. SIG’s Fire Control Unit is designed for simplicity. It can be removed and transferred to another SIG pistol if desired – customization at its finest.

Notice also the lack of a hammer. This is a striker-fired handgun with fast lock time. The slide release is ambidextrous, located on both sides of the frame. The magazine release is reversible. Lefties need not be concerned.

I like the way it feels in my hand. It is solid with some heft to it. The slide is blue stainless steel, and the frame is Nitron-finished. When fired, I sense this as it absorbs recoil and seems more accurate. The grip frame is slightly more than an inch wide, making it easy to carry concealed.

Although this pistol is equipped with standard iron sights, the P320 has a rear sight plate that is replaceable by one that will allow mounting of an optical sight. This gun groups well with irons. It is a mid-size gun but feels solid in my hand and returns to zero from shot to shot. Its fine-checkered grips aid in a firm hold while firing and allow good recovery from recoil.

Notice the extended beavertail grip. It prevents the slide from biting the web of my hand upon firing. SIG has done a nice job of thinking out what shooters will need to carry this pistol.

Shooting the P320 is like shooting a good double-action revolver. The trigger is curved steel that breaks like a revolver trigger would, but I have 17 rounds loaded instead of six. The steel magazine is well-made, adding to the gun’s reliability. SIG sends three with each gun. I like that!

Here at Arizona’s famous Area 51 near Tucson, I have set up steel plates, paper targets, and some infamous 2-liter soda bottles. They are no match for the SIG! 

As I aim and squeeze, I anticipate recoil, but it is light from this 9mm. My confidence increases with each shot as steel rings and soda bottles explode with first-shot regularity. The open sights are quick to pick up and make shooting easy.

This gun is accurate! Hitting the steel plate is easy and even the small “flapper” can be engaged effortlessly. The milk-bottle-shaped steel target gives a pleasant ding per hit. My favorite targets are the 2-liter soda bottles. No doubt about the power of a 9mm as they explode when hit. 

Shooting targets with the SIG is fun. (I cannot believe they pay me to do this!) I must admit that I am an old Glock guy with an old Glock. However, after shooting the SIG today I would not hesitate to carry it.

Although I did experience one stovepipe jam, I feel that reliability is high with the SIG. The case cleared quickly, and I was back in action. Any semi-auto pistol is only as good as the ammo you feed it.

Although I like a full-sized carry gun, the SIG P320 has some big features that are appealing. Solid steel construction and nicely checked grips allow for good shooting control. It is simple to aim and fire. 

Like a double-action revolver, there are no unneeded safeties. It is a lightweight, clean-looking pistol that carries well concealed. Customizable to suit left-handed shooters, it includes SIG’s Trigger Control Unit, which is transferable to other SIG pistols. Caliber conversion kits are also available. 

Sometimes we tend to select a gun based on its low cost. This pistol is high quality at a bit higher cost, but well worth the money if you intend it for personal defense. Pick one up and you may agree that the SIG P320 is well-designed and all quality.
