Sig P320 X Carry Review

The Sig P320 X Carry is an extension of the Sig P320 line, and we’re going to cover it in our Sig P320 X Carry Review. The Sig P320 was designed and based on the Sig P250, a commercially unsuccessful double action only modular handgun that Sig designed in the 2000s.

Sig took their failure with the Sig P250 and redesigned it into the Sig P320 line. The Sig P320 is a striker-fired handgun that is now the official firearm sidearm of the US Army in the M18 variant. With the Sig320 success on the military and law enforcement market, they also have quite a hold on the civilian market.

One of the most popular parts of the Sig P320 category is an upgraded performance line called their X series of the Sig P320.

The flagship of the X series is the Sig P320 X5, but they developed the Sig P320 X Carry as a smaller carry option that took advantage of many of the features of the X 5 series.

Their most notable feature is the frames. Sig designed the frames completely differently than the normal Sig P320 frame. They feature a large beavertail that allows you to get a little bit higher grip on the gun, and the ergonomics are more Glock-like, allowing the shooter to get more control over the firearm.

The X Carry has a 3.9-inch barrel and also comes standard with an optic cut. Those are just some of the items that set the gun apart from its Sig P320 brethren.

Role

The Sig P320 Carry runs the fine line of working for both duty and concealed carry. It’s a great do-all gun. It feels equally at home on a battle belt or in a P320 X Carry holster for concealed carry.

The wide width makes it a little wide for concealed carry for some people but it can definitely be done. With a good holster with adjustable cant and large enough clothing, it’ll conceal well for larger individuals.

AIWB is the preferred concealed carry method for most people concealed carrying the X carry. With the right holster, it conceals surprisingly well.

Features

The Sig P320 X Carry uses a flush-fit 17-round magazine. The 17-round metal magazine isn’t the only magazine option for the Sig P320 X Carry. Sig also makes factory 21-round magazines for this gun.

I will warn you though the Sig 21-round factory extended magazines may or may not be legal for USPSA.

These magazines fit right on the 140-millimeter length restrictions, and people have had issues with some of the magazines not fitting within the gauge. So, you may have to sand down the base plates a bit if they do not fit.

Right now, there are not many aftermarket options for the Sig P320. You can purchase aftermarket extensions for the Sig P320 mag to get a little more capacity out of the magazines.

But, besides that, there aren’t many aftermarket options and one disadvantage of the Sig design is you can only buy the magazine straight through Sig themselves, and they aren’t cheap running between 38 and $45. The good news is that the magazines are offered with various baseplate colors, including black and FDE.

So, you can match the baseplate of your magazine to the color of your frame, or you can do like I’ve done and provide a little contrast by using a baseplate that is different from the color of your frame. Magwell, the Magwell on the Sig P320 X Carry is actually quite good.

Magazine Well

There’s a nice bevel at the bottom of it, and while not as good as a Glock 19 Gen 5 MOS, it’s probably the second-best Magwell in the striker fire category. I really don’t have any complaints about the system, and it is a cut above the rest minus the Glock.

Grip/Ergonomics

Grip Modules

The Sig P320 X Carry does not feature any removable backstraps like most of its striker-fired polymer frame brethren.

It does give you the ability, though, to switch out frames. The Sig P320 is a modular system and the major advantage of that is it’s easy and affordable to switch out frames.

Sig P320 X Carry frames will run you around 45 to $50 and they are readily interchangeable.

They only make the X range in the medium size and not in the large or small sizes. This may change in the future. That means you don’t really have that many aftermarket options. You can always switch the frame to a standard Sig P320 carry or compact frame or a Sig P320 X Compact frame.

But, there aren’t a lot of options outside of that. If you want to try stippling the frame yourself or have the frame send out to be stippled, it’s nice that you don’t have to send the entire gun off when doing so, and you can send it straight through a post office and don’t have to use an FFL since the frame itself is not a registered part of the firearm.

There’s a nice beavertail at the rear that does seem to allow you to get your hand a little bit higher than the standard Sig P320 frame allows. The ergonomics themselves are somewhat similar to a Glock Gen 5 in a weird way.

It’s funny that the Sig P320 performance line is similar to a Glock. In my opinion, the regular Sig P320 frames feel more comfortable than the Sig P320 X frames.

That said, I shoot the Sig P320 X frames way better as they allow me to get my hands in all the right places to get leverage and control the gun under recoil. There is sufficient texturing on the gun on the front and back strap and the side straps.

It’s not great, but it feels kind of like that not very aggressive sandpaper. It’s enough to keep your hands in place, but it’s not going to bother your hands at all.

Texturing

Frankly, it’s the bare acceptable minimum amount of traction you would expect on the grip of a gun, better than a lot of options, but not as good as some of its competitors like this CZ P10. C, which has the best factory texturing on the market.

Overall, the general feel of the gun is good, and it’s a gun that you can really control well, which is my favorite feature.

The gun isn’t going to win any points over the same P320 in general hand feel, but as far as control, you seem to be able to get those fingers in all the right places to keep the gun still while firing it.

Sig P320 X Carry Review Sights

The Sig P320 X Carry comes with SigLite night sights. The SigLite night sights are a front green tritium site with a green luminescent ring around it, and they’re not quite as bright as the yellow Trijicon HDs, but they’re still brighter than most factory white dot night sights that most guns come with.

The rear sight on the Sig P320 X Carry is mounted to an optics plate cover, and that side has two tritium vials at the rear with no coloring around them. So, they provide a nice black sight, nice black rear sight with a high contrast front sight during the daylight.

They really are decent sight pictures. The sights on the Sig P320 X Carry aren’t great, but they’re definitely so good that you won’t want to spend the money to replace them, or at least it will be hard to justify the money to replace them.

If you plan to replace your Sig P320 X Carry sights, you don’t really have the option and the reason is the rear sights are mounted on the optics plate cover of the pistol.

Sig P320 X Carry Optic

So, all you can really do is replace the optics cut cover with an actual red dot. In my opinion, this is way superior to having a nice rear iron sight. The Sig Romeo1 actually has a notch built into the rear of the gun for a crude iron sight picture that does seem to work with the front sight.

Your elevation will likely be a bit off, but it definitely keeps your horizontal string of fire where you want it to be. So, as backup, iron sights will work, especially if your target is up close in a self-defense situation. Hopefully, you’ll only need your Sig P320 backup iron sights if the dot fails, but the dot is unlikely to fail.

Controls

Sig P320 X Carry Review Safeties

There are no external safeties on the Sig P320 X Carry. There isn’t even an external trigger safety like most other guns. The trigger itself is somewhat lighter than most other striker-fired guns as far as the trigger shoot, not the trigger pull.

So, in theory, this helps the gun be drop safe because the trigger should not continue to travel with momentum like many other heavier triggers might when dropped.

I’m still a little bit iffy about this. But that said, in my testing, I haven’t found any issues, but I haven’t exactly dropped the gun onto a hard surface from a high height either.

Magazine Release

The Sig P320 X Carry magazine release is located in a standard push-button position for most guns.

The nice thing about the magazine release is I can just hit it with my thumb without breaking my grip. I have medium to large-sized hands, and anybody with hands smaller than me would not be able to do so.

That said, it’s straightforward to readjust your grip even if you have to break it and continue firing once you’ve reloaded. The magazine release itself is reversible to the other side and it’s frankly an excellent design. Edges are well-rounded. There’s nice texturing on the front of it and I can’t think of any way Sig could do better for a factory gun.

You could put an extended slide release, but there’s really no reason for it to be any more extended or any more recessed.

I think Sig did an excellent job on this feature.

Sig P320 X Carry Review Slide Lock

The Sig P320 X Carry slide lock is ambidextrous, and it’s basically mirrored on each side.

The slide lock itself locks into a cutout on the left side of the Sig P320 X Carry slide. This means that a right-handed shooter will have a little easier time dropping these slides than a left-handed shooter.

That said, it’s easy for both right-hand and left-handed shooters to drop the slide using the slide lock. The slide lock itself is somewhat low profile but features a nice angle on the top that is easy to access with your firing hand thumb.

Personally, I really like it, and I think it’s well-positioned. Unless somebody has tiny hands, they’re not going to have an issue with this design. Overall ergonomics. Overall ergonomics of the Sig P320 X Carry are excellent unless you have super large hands.

Sig P320 X Carry Bore Axis

The issue for somebody with super large hands is the distance from the bottom of the grip to the bottom of the trigger guard undercut is about as long as a Glock 19, despite the gun itself being the size of a Glock 17 in terms of the height from the bottom of the magazine to the top of the slide.

The reason for this is the Sig P320 X Carry has a fairly high bore axis.

So, the slide and a major portion of the frame keep your grip from getting that high on the gun. While this is not a deal-breaker for many, it is something you have to take into account. This gun fits my hand, similar to how a Glock 19 would despite being much larger.

So, if you’re looking for the most efficient concealment gun that you can get your hand on, this might not be the best choice for you.

Trigger

The Sig P320 X series ship with a flat-faced trigger, and it’s really nice to touch. It works really well, and it’s ergonomic. The trigger itself is nothing special, and it’s pretty much a standard striker-fired trigger.

From the beginning of the trigger pull, you’re going to feel a little bit of very light take up that’s very short, and then you’re immediately going to hit a wall, and from that wall, you hear creep, creep, and more creep until you get a very rolling break after around three portions of creep.

Every trigger is going to be a little bit different. But, the trigger pull itself is fairly short and from the reset, you’re pretty much immediately come back to that wall before filling the creep again and finally going into the rolling trigger break.

Again, the trigger is good. It’s a great self-defense trigger. But, if you’re a trigger snob, you’re likely going to want to replace it with parts from great guns.

Sig P320 X Carry Review Maintenance

Cleaning the Sig P320 X Carry is fairly easy. You’ll need to take out the mag, ensure the gun is clear, lock the slide to the rear, and then rotate the takedown lever down 90 degrees. The lever can be a little bit hard to turn at first, but eventually, it does break in.

Drop the slide forward, and it comes right off without deactivating the striker by pulling the trigger. So, this gun can be completely taken apart without pulling the trigger, which is a nice feature for many people. The system itself is also straightforward to get inside and clean. I have no issues with the Sig P320 system, and I think it’s a brilliant design as far as modularity.

Aesthetics

Overall, the Sig P320 X Carry aesthetics are second to none in its class, in my opinion. The X Carry laser etching is a little bit gaudy. Besides that, the forward and rear serrations look great. The frame itself is attractive.

Overall, I just really liked the look of the gun. One of those things, I could see how some people could think that polymer on the frame seemed a bit cheap, and it does feel a little bit cheaper than other guns. But, overall, the gun does look good, especially from a distance.

Sig P320 X Carry Review Shooting

Shooting the Sig P320 X Carry is a dream. The gun has an extremely light recoil impulse. Now, the recall on the gun is light as far as felt recoil, but the gun seems to cycle a little bit slower than something like a Glock, and it does have more muzzle rise. But, for newer shooters, this might be a great centerfire gun to start with, as the recoil is a lot more approachable than something like a Glock 19 that seems just a little more violent to the shooter.

I really like the Sig P320 X series, and frankly, the gun shoots itself. It’s so easy to shoot. Honestly, if there’s any gun that I could see replacing my Glock 19, it would be the Sig P320 X Carry.

That said, the overall size is similar in size to a Glock 17 makes it a hard choice to do so, with the Glock 19 being just a little bit shorter and giving me a little more room for error in concealment.

I like the Glock 19 a little bit better than this gun due to the size and usable grip length. But, if I can get the size of the Glock 19 with the shoot-ability of the Sig P320 X Carry, I would choose the X Carry all day long. For those with Smaller hands, check out the Sig P320 X Compact.
