Sig P250 vs Sig P320

Hello there to you all, and welcome to this review of two top-class handguns on offer today. The two pistols in question are from the highly regarded, leading Swiss firearms manufacturer Sig Sauer.

Sig Sauer somehow keeps on amazing us, by managing to raise the bar higher with each new gun model they produce.

In this review, we will be looking at and giving you an insight into, what makes both choices of gun special. We will be pointing out the differences between the two models and offering an overview with our opinions as to which may be the gun best suited to you.

No two guns are ever fully equal, however. Today we will take a closer look at a couple of their excellent models of weaponry. Let us introduce you to the…

Sig P250 and The Sig P320

Before we move on to look at each gun individually, let us first point out the main difference between the two.

The P250 is an older model design. And the firing of this pistol relies on the hammer system. While on the other hand, the P320 is an upgraded version of the P250 and makes use of the striker system.

Both these guns are dependable and fully competent weapons, that just have that one crucial difference to their design. This difference in itself may not sound too much to someone not familiar with pistol shooting. But those of you in the know will realize it is a major point to consider when discussing and considering a new gun purchase.

OK, let us move on and take a closer look at each pistol individually…

Sig Sauer P250

First to go is the Sig Sauer P250. As said, this is an older design of gun that caused a lot of excitement when first released in the world of gun lovers back in 2007. At that time it really caused quite a stir with its revolutionary new design. It was innovative, and Sigarms saw potential in it at a time when concealed carry laws were changing.

The Sig P250 led the way with a new breed of guns, becoming one of the first modular handguns to be released upon the world.

The P250 has a steel-framed control unit. This is the primary module that you can then customize to your own specifications and preferences. Choose this model, and it gives you the option of changing slide sizes, the polymer grips as well as even the chambering system. And you are able to set up the chambers to hold anywhere between six and seventeen rounds. Now that is a pretty wide range of choice.

Pick up a P250, and you can feel at once you are bearing a serious piece of kit. For recreational purposes, this is a gun that is able and superb for use. But what we are looking at here is a gun with a purpose – and that purpose is self-defense.

A full combat weapon that has been built with the intention of being by your side in life-threatening situations. Ready and waiting to save your life if ever you find yourself in real danger. With that in mind, Sig Sauer did not add any kind of manual safeties. Nothing is there to hinder or slow you down in those critical moments when you least need to be.

Now then, what is it like to actually use this piece?

The modular design makes for a very user-friendly weapon. Disassembly requires no tools, and even changing the caliber can be done in just a matter of minutes. This means that if you are ever in a situation that calls for you to swap out for a different caliber, you can switch from .40 to .357 within a minute. Now that is what we call a fine feature.

If you were to buy a P250 for your own use, you will first have to practice and then keep practicing. This is to become accustomed to the hammer double-action system. The trigger has a lot of travel before firing. Once you have sussed it out, then you will find this a pleasure to shoot.

Accuracy, of course, relies on the user, but this gun gives you the confidence to fire off and hit your target. It is able to drive a nail into a piece of timber from 50 feet away. There is a challenge for you. Ha, go on, go and see if you can do that! Believe us when we say it can be done with the P250.

We now ask how tough and reliable this gun is?

Well, the answer is extremely. The P250 is a very durable gun that, if kept clean and well maintained, it will not break down on you.

It will suit casual shooters and pros alike. A gun that you can rely on for shooting targets out on the range. Equally so to be relied upon under heavy fire while on patrol in some dingy downtown ghetto. A gun that can excel in both worlds.

It is very comfortable in the hand for use. The design is very boxy though, due to the modular system so, to some, it is considered an unattractive pistol. The good thing is, if you are not 100% comfortable with one grip, you can swap it out. The whole range of options the P250 offers means you really can personalize this to your own standards.

For an ‘old boy on the block’ the Sig Sauer P250 still ‘stands tall.’

OK, so now let us move on and take a closer look at the Sig Sauer P320…

SIG Sauer P320

The P320 is very much the same gun as the P250. It uses the same modular system, and it has the ability to be customized in the same manner to please your own objectives of what you want in a firearm.

So, what is it that makes them so different if they are so similar?

Well, it lies in the firing system. A P250 has a recessed spurless hammer system in operation, whereas the P320 makes use of a more modern striker system design. So which gun you decide on will all boil down to which firing system you prefer.

Let us explain in a little bit more detail…

On the whole, a striker system is faster to the draw. It is basically ready to shoot off a round the instant it is in the chamber. More experienced users really do love this fast-action feature, but before you go getting all ‘gung-ho,’ there is one major safety issue that needs to be considered.

Guns that use the striker firing system are much more likely to fail drop tests under certain circumstances. To reduce this risk to a minimum, we suggest opting for a lighter trigger, as it won’t fire off if the gun hits the floor under the right angle. Using a tabbed trigger is always your best choice when it comes down to this issue of safety.

Let us move on and take a look at performance differences between the P250 and the P320.

On the release of the Sig Sauer P320 pistol, the company made the bold claim that this was the most accurate striker-fired gun offered on the market. Owners and users of this pistol really do give rave reviews as to its accuracy. You need to remember, though, that accuracy improves with use, time, and experience. If you perceiver and stick to these three points, you will be hitting bullseyes wherever you aim the gun.

It is able to be adapted to fit all the same calibers as well, using the same Sig caliber X-change kit as the P250.

Obviously, you need to keep your gun in order to get the maximum from it. Routine cleaning and oiling will ensure that the weapon is always at the ready to give you optimum performance. With that in mind, why not check out some of the best gun oil and grease after you finish this review?

Sig P250 vs Sig P320 Conclusion

Let us now bring these guns back together to make a few comments before we round up this review.

Both the P320 and the P250 are ‘well up’ for the job. Whether you are a hobby target shooter, a private citizen who feels the need for protection or you are a professional officer who wants the ultimate backup weapon. Whichever you may be, we cannot say specifically which one you should choose. At the end of the day, choosing a firearm needs to be the decision of each individual.

We recommend if at all possible to handle both of them and even fire off a few rounds. That is the only way you will fully understand how two very similar looking and designed guns can actually be so different.

We do hope we have been of help in this feature on the Sig P250 vs Sig P320.

As to which is best…? That is for you to decide.

Thanks for sticking with us, Safe shooting. Check us out next time.
