What Is the Difference Between SIG P226 and SIG P320 Based on Features?

Let’s check out the difference between these guns through their specs-

Feature 1: Modular Fire Control Unit with Interchangeable Frames

The SIG P226 is a metal-framed, hammer-fired, double-action pistol. It is designed with non-modular internals and you will not be able to interchange its frame, slide, barrel, or other major components.

On the contrary, if you check the SIG P320 pistol’s design and available features, you will notice that it is a full-size polymer-framed hammerless striker-fired pistol. The P320 is designed with a Modular fire control unit which means you can purchase a new slide, barrel, or frame to turn it into a compact carry pistol because this gun lets you interchange (the serial number must match with the replacing part) its factory-assembled major components.

Therefore, if you compare these two’s manufacturing designs and features, you will see the obvious differences between them. Both are designed incredibly and ensure excellent reliability, but the SIG P320 is a newer version and offers more options in terms of interchangeability. 

Feature 2: Percentage of Metal and Magazine Capacity

The SIG P226 is designed and built with a significantly higher ratio of metal and it makes the gun quite heavier than the P320 gun. Not only that but the P226 also has only a 15+1 magazine capacity which is less than the P320. But the P226 is not as chunky as the P320 and is thinner than the P320 version.

On the other hand, the SIG P320 is a polymer-based (polymer-made frames) gun, but the main components, such as the slide, springs, and barrel are made of metal. That means it has a significantly less percentage of metal and is lighter than the P226. Also, the SIG P320 has a bigger mag capacity of 17+1.

Therefore, if you are looking for a heavier but thin pistol with a decent mag capacity, P226 is better. But if you are interested in lighter and need a higher mag capacity, the P320 will be better for you.

Feature 3: Single-action/Double-action (SA/DA) & Legion Configuration

The SIG P226 pistol can either be a single-action/double-action (SA/DA) or a single-action only (SAO) configuration. Besides that, it also features Legion configuration (which means the gun contains an upgraded trigger, grips, sites, and tuning).

On the other hand, the SIG P320 pistol’s trigger pulls generally stay somewhere between the single-action or double-action (SA/DA) and is a cheaper version especially because of the Polymer. Also, it does not have an upgraded legion model, but users can enjoy the advantage of the Modular system.

If you desire Legion configuration over modularity, then the P226 is a better choice, but if you prefer modularity, go for the P320.

SIG P226 or SIG P320 – Which One to Choose?

It is really impossible to pick one between these two based on which one is better than the other concept.

Because both pistols are designed with upgraded and improvised features like optics-ready configurations, which means both are equally reliable. 

Therefore, it solely depends on the users’ preference to claim one over another as “the better option”.

Some users might prefer polymer-framed, striker-fired pistols and the P320 will become a better choice for them.

Another thing is, the P226 absorbs the recoil better than the P320 because it is more solid than the P320.

On the contrary, the P320 offers more flexibility and allows customizing the gun based on your preferences.

Other users might like a gun with a higher percentage of metal and feels a little heavier the P226 is the ideal option for those consumers.

Similarly, some people prefer having a DA/SA system on their handguns and the P226 will be better for them.

While considering the price difference between these two, the SIG P226 is more expensive than the SIG P320, and if you are interested in a more affordable gun, the P320 is better.

You might also consider how upgraded and improvised each of these pistols is because they both have some individual benefits that are missing in the other.
