Design and Build Quality

The SIG Sauer P320 M17 is a beast of an airsoft gun. I’ve been using it for quite some time now and I’ve got to say, it’s a solid piece of kit.

First off, the design of this gun is top-notch. It’s got that authentic SIG Sauer look, which is a big plus for me.

It’s a 1:1 replica of the real deal, and it shows. The attention to detail is impressive, from the trademarks to the serial numbers. It’s not just a pretty face though, this gun is built to perform.

The M17 is a good size, not too big, not too small. It feels great in your hands, very sturdy, no wobbling anywhere.

It’s got a nice weight to it, nicely balanced, which makes it comfortable to handle for extended periods. The grip is a medium Sig grip, so it should feel comfortable in most hands.

Now, let’s talk about build quality. The M17 is built like a tank. The slide is metal and the grip is Sig’s standard polymer grip.

There’s no wobbling or wiggling of the slide or outer barrel, which is a common issue with many other airsoft pistols. This thing is solid.

The external durability is excellent. The internal components are also robust. The trigger pull requires very minimal pull, adding to how smooth everything is.

The magazine is a bit of a mixed bag. On one hand, it’s nice and heavy, feels sturdy. On the other hand, it’s a bit tricky to load if you don’t have nails. But once you get the hang of it, it’s not a big issue.

The M17 comes with a threaded outer barrel, which is a nice touch.

In conclusion, the SIG Sauer P320 M17 is a well-designed, high-quality airsoft gun. It looks great, feels great, and performs great.

Shooting Performance

Alright, let’s talk about the shooting performance of the SIG Sauer ProForce P320 M17.

First off, the accuracy of this beast is something to write home about. I’ve been using it for a while now, and I can tell you, it’s a laser.

Whether you’re shooting at a target 50 feet away or trying to hit that sneaky opponent hiding 100 feet away, this gun delivers.

The BBs fly straight and true, and they don’t start to drop until they’re well past the 100-foot mark.

This gun has got some serious reach. I’ve been able to hit targets consistently at over 100 feet. That’s pretty impressive for an airsoft pistol.

And the best part? The range doesn’t come at the expense of accuracy. Even at long distances, the BBs hit where you aim.

Reliability is another strong point of the P320 M17. I’ve put thousands of rounds through this gun, and it’s never let me down.

It just keeps on shooting, no matter what. I’ve used it in all kinds of weather, and it’s never missed a beat.

The trigger on this gun is a dream. It’s crisp, with a nice break and a short reset. This makes rapid firing a breeze. I’ve been able to triple tap targets at close range with ease.

One thing that really stands out about the P320 M17 is its gas efficiency. I’ve been able to get about 3 1/2 mags worth of shots from a single CO2 cartridge.

That’s pretty impressive, especially when you consider the power and range this gun has.

The hop-up on this gun is easy to adjust, which is a big plus. It allows you to fine-tune your shots, ensuring that you hit your target every time.

Another thing to note is that the gun is pretty loud. Some might see this as a downside, but I actually like it. It adds to the realism and makes the gun more fun to shoot.

In conclusion, the SIG Sauer ProForce P320 M17 is a top-notch airsoft pistol when it comes to shooting performance. It’s accurate, has a great range, and is incredibly reliable. Sure, it has a few quirks, but they’re minor and don’t detract from the overall performance of the gun.

In fact, this replica is included in our ultimate list of best airsoft pistols overall, as well as the best GBB pistols in airsoft.

Shooting Performance: 90/100


Let’s talk about the realism of the SIG Sauer ProForce P320 M17. Now, I’ve been around the block a few times when it comes to airsoft guns, and I can tell you, this one is a real treat for folks who value authenticity.

First off, the weight and feel of this gun are spot on. It’s got a nice heft to it, just like the real M17. You pick it up, and you know you’re holding something solid.

It’s not just the weight, though. The balance is just right, too. It sits comfortably in your hand, and when you bring it up to aim, it’s like an extension of your arm.

The attention to detail is impressive. You’ve got all the right markings and serial numbers, and the slide action is smooth and satisfying.

It’s got a nice kick to it, too. You pull the trigger, and you feel it. It’s that kind of realism that really immerses you in the game.

Now, let’s talk about the internals. This gun is a 1:1 replica, and that extends to the inside as well. The disassembly is the same as a real M17, which is a big plus for maintenance and any potential upgrades.

It’s a nice touch that adds to the overall realism and functionality of the gun.

Another thing I love about this gun is the magazine design. The extended mags are just like the ones you’d get for the real M17.

They fit snugly in the mag well, and they give the gun a distinctive look. Plus, they’re versatile. You can use either green gas or CO2, depending on your preference.

The realism doesn’t stop at the look and feel, though. This gun performs like the real deal, too. The trigger pull is minimal, which makes for smooth, fast shooting. The blowback is strong and snappy, which adds to the overall feel and performance of the gun.

Now, no gun is perfect, and there are a couple of things to be aware of. The white dotted sights can be a bit hard to see in the dark, but they work fine in daylight or under some lighting.

But, these are minor issues in the grand scheme of things. In conclusion, the SIG Sauer ProForce P320 M17 is a fantastic choice for airsofters who value realism. It looks, feels, and performs like the real deal, and it’s a joy to use on the field.

Maintenance and Durability

Alright, let’s dive into the maintenance and durability of the SIG Sauer P320 M17.

First off, I’ve got to say, this airsoft gun is a real trooper. I’ve been using it for a good while now, and it’s been through some rough times.

But guess what? It’s still shooting like it’s brand new.

The M17 is a sturdy piece of kit. I’ve dropped it more times than I can count, and it’s shrugged off every single fall.

It’s like the thing is made of adamantium or something. I’ve seen some airsoft guns that start to fall apart after a few rough games, but not this one. It’s a real survivor.

Now, let’s talk about maintenance. I’m a big believer in taking care of your gear, and the M17 makes it easy. It’s simple to break down for cleaning and maintenance, and it doesn’t have any weird quirks that make it a pain to work on.

I’ve had some airsoft guns that were a real headache to maintain, but the M17 isn’t one of them.

But, I’ve had a few minor issues with the M17. For one, the magazine can be a bit tricky to load if you don’t have nails. It’s not a deal-breaker, but it can be a bit annoying.

Another thing is the feed lip on the magazine. I’ve heard from other players that it can break if you’re not careful.

I haven’t had this issue myself, but it’s something to be aware of. The solution is to pull the spring slightly down and load BBs into it through the feed lip.

In conclusion, the SIG Sauer ProForce P320 M17 is a durable and reliable airsoft gun that’s easy to maintain. It’s not perfect, but its minor flaws are far outweighed by its strengths.

Maintenance and Durability: 80/100


When it comes to customizability, the SIG Sauer P320 M17 is pretty great. It’s got a few features that make it a joy to tweak and personalize.

First off, the M17 is red dot compatible. This is a big deal for those of you who like to dial in your aim with precision optics. The slide has an actual RMS mounting point for real red dot sights.

This means you can slap on a sight that suits your style and needs, and you’re good to go. It’s worth noting, though, that finding holsters that fit with the RDS can be a bit of a challenge, but not impossible.

Another aspect of the M17 that lends itself to customization is its modular design. This gun is built to be taken apart and put back together again.

It’s easy to field strip and clean, and the takedown pin twists in place, so you don’t have to worry about losing it. This makes it a breeze to swap out parts or perform upgrades.

The M17 also comes with a threaded outer barrel. This is a nice touch for those who want to add a suppressor or a tracer unit. However, be aware that the barrel threading on the gun is 13mm NEGATIVE, which means you might need an adapter to fit some accessories.

One more thing that adds to the M17’s customizability is its compatibility with both green gas and CO2 magazines. This means you can choose the type of gas that suits your play style and the conditions you’ll be playing in.

In conclusion, the SIG Sauer ProForce P320 M17 is a highly customizable airsoft gun that offers a lot of options for players who like to personalize their gear.

Customizability: 80/100


Let’s talk about the price. Now, I’ve been in the airsoft game for a long time, and I’ve seen guns that cost an arm and a leg.

But the P320 M17? It’s a steal. For the quality and performance you’re getting, the price tag is more than fair.

It’s not the cheapest on the market, sure, but remember, you’re paying for a top-notch piece of kit here. It’s a solid investment, and in my experience, it’s worth every penny.
