Sig P320 Review [2020]

The SIG Sauer is a handgun originally designed with military use in mind. Given its popularity among law enforcement and the general public, we wanted to undertake a SIG P320 review to see what the weapon is really all about.

Our SIG P320 review takes a look at the popular handgun’s modular design that lets you change the caliber and size of the gun to meet your individual needs. This gun is large enough for home defense while being small enough for many individuals to conceal and carry.

We also looked at some of its features, such as the three-point take-down safety system that keeps the piston from breaking down when a magazine is still inserted or if the slide is locked to the rear.

This SIG P320 review will demonstrate that this is a customizable pistol that meets a variety of needs; but how does it compare to similar competitors?

What Is the SIG P320?

The SIG Sauer P320 pistol is used by government agencies as well as sportsmen for its efficiency, adaptability and customization. The SIG Sauer P320 comes in four different sizes: Full Size, Carry, Compact and Sub Compact. For our SIG P320 review, we looked at the full-size and compact model, each chambered for 9mm cartridges. The models also come in .40 and .45 as well.

The SIG Sauer P320 is a striker-fired pistol with a polymer frame. The polymer is fiberglass-reinforced, and the full-size SIG offers a sturdy rail for accessories. The SIG system has a barrel and chamber titled downward from the slide at the time the gun is fired. The striker is cocked every time you rack the slide. The full-size SIG comes with 17-round magazines, while the compact offers 15 rounds.

Grip and Feel

SIG’s grip options come in a variety of sizes and switching grips in the SIG P320 review was easy to do. Changing the caliber is also user-friendly with the SIG P320, as the pistol offers guaranteed modularity.

Textured panels are round on each side of the handle as well as the frontstrap and backstrap. The magazine release is reversible for right- and left-handers. All the SIG’s features are ambidextrous. The trigger guard features an upward curve with a deep undercut for a high, comfortable grip. This also helps control recoil.

Durability and Performance

The slide is made of a high-grade stainless steel with bevels that run the length of the unit, and it features slide serrations on the front and rear. The slide has a Nitron finish to defend against corrosion. The Nitron finish involves heat treating the steel with a chemical bath in order to create a very hard oxidized surface.

A sturdy three-dot sight system sits atop the slide. Windage can be adjusted by drifting the dovetail sights. Both models of the SIG Sauer P320 consistently scored well on accuracy in a range of weather conditions. Recoil is minimal in both models, and the iron sights useful to most shooters.

Depending on the size of your SIG Sauer P320, the striker-fired autoloader has a magazine capacity of 12 to 17 rounds.
The length of the gun ranges from 6.67 inches to 8.05 inches. The barrel length runs from 3.55 inches to 4.7 inches, and the gun’s height range is 4.29 inches to 5.51 inches with a maximum width of 1.38 inches.
Unloaded, the SIG Sauer P320 weighs from 24.9 to 27.6 ounces. The trigger pull weight tests at about 6.88 pounds. Safety features in the SIG P320 review included an integrated trigger safety and automatic firing pin block.

Pricing

The manufacturer’s suggested retail price for the SIG Sauer P320, depending on the model, ranges from $597 to $679. During our SIG P320 review, we found a number of SIGs for sale around $530, and one listed near $500.

Ease of Use [***]

The SIG Sauer P320 is comfortable in the hand with grip panels that feel like non-slip floor tape. Serrations in the slide help with gripping and pulling, but it can still be difficult for weaker shooters to pull. During SIG P320 reviews, sweaty hands also caused problems despite the serrations.

Glock 19 Gen5

Conclusion: SIG P320 Review

After completing our SIG P320 review, we confidently give the SIG Sauer P320 four stars. Its incredible adaptability and customization are as good as any in the business, from calibers to sizes to grips.

A shooter never again has to worry about the width or circumference of grip with SIG’s interchangeable modules. Convertible calibers include 9mm, .357 SIG, or .40 S&W. Even the pistol sizes range for your preference from full-size all the way to subcompact.

This SIG P320 review also alerted us to the accessory rail. This is one of the most stable systems we have seen and great for lights, lasers and other needs.

Also, it should not go unnoticed that SIG went out of its way to put safety first. The Striker safety does not allow the pistol to release until the shooter pulls the trigger. SIG worked hard to make a great pistol, and they have succeeded.
