Sig P320 X5 Legion Holster

Contender Sig P320 Legion

Overview

 

The Sig P320 X5 Legion is an improved version of the Sig P320 X5. These pistols are the competition line of the Sig P320 series.

Sig built its legacy on the famous Sig P226 that gained most of its notoriety from being the standard-issue sidearm of the Navy Seals. They had significant success with a more compact version of the Sig P226 the Sig P229 that was issued to the US Air Marshals. Before the Sig P226 and P229, their most notorious pistol was the Sig P210 a single action only pistol carried by the Swiss Military and Police.

Sig USA is an offshoot of the original European Sig that has since grown leaps and bounds past the company that gave them their name. Sig USA originally started as the US Importer for the European Sig and due to the Europeans lack of understanding of the US Market Sig USA ended up Separating from the European Sig. Sig USA became making the Class Sig P226 and Sig P229 guns in the US while still importing higher-end variants of those guns from their European counterparts. At the time Glock, Springfield Armory, and Smith and Wesson were selling polymer striker-fired handguns that were much cheaper than Sig’s offerings.

Sig introduced the modular Sig P250 platform that was the precursor to the Sig P320. The Sig P250 was a DAO(Double Action Only) pistol that had a serialized chassis so you could buy frames and slides over the counter without having to buy another gun. The selling point was for restrictive areas that made it hard to buy more than one gun you could have one gun that could be configured for any mission. Considering it’s relatively easy to buy guns in most of the US and the cost of a new frame and slide was basically as much as a new gun the P250 didn’t do well on the US market. Consumers also complained about the heavy DOA trigger.

Sig learning from the failings of the P250 introduced the Sig P320 series that still had all the great versatility of the P250 but with a striker-fired trigger that was more acceptable to the American Consumer. Sig pushed the modularity for the ease of modification vs trying to sell caliber and size exchange kits that cost as much as the gun. They released difference sized frames that could be purchased from amazon or other online retailers for under $50. If a user wanted to get their gun custom stipped they could send off their frame without having to send off the serials part on the gun. If they wanted to try modifying the frame on their own they would only be out $50 if they messed up instead of the cost of the entire gun.

The Sig P320 began to gain a lot of traction on the US Market. Sig eventually introduced a new line of frames that they called their X frame for more performance-oriented shooters. One of their gun offerings with this frame was the Sig P320 X5. The Sig P320 started to become a very popular option in the high growth USPSA Division called carry optics.

Sig had started a premium line of firearms they called the legion line that was relegated to the hammer-fired guns. USPSA carry optics at the time had a weight limit for the guns of just over 40 ounces and the popular polymer guns weighed in well under that limit. Sig saw an opportunity to get innovative and introduced the Sig P320 X5 Legion to appeal to USPSA carry optics competitors as well as their higher-end legion customers.

Holster Design

Contender Sig P320 LegionThe Sig P320 X Legion is an extremely heavy design so you must make sure your gear is set up to support the weight. You’ll want your Sig P320 X5 Legion holster to be built from Kydex that is .093 inches or thicker. The .093 inch Kydex is really sufficient for a heavy gun you’ll get a lot better retention than if you move up to something like .125 which doesn’t have a lot of flex so it’ll have more friction when you’re drawing the gun.

With its firing pin block safety, people use the Sig P320 for a variety of uses including duty and tactical use including concealed carry. For applications that require an overt OWB holster, it’s helpful to have a Sig P320 X5 Legion holster with a versatile mounting pattern. With a versatile mounting pattern, you can use multiple belt mounts on the holster tailoring the holster to your specific mission.

If you’re a competitor shooting USPSA Carry optics you’ll want to set up you Sig P320 X5 Legion Holster with a Turbo Drop or Boss hanger and mount it to an extremely stiff competition belt. This setup will allow you to optimize the placement of your holster for a smooth draw while keeping everything rigid. It’s a little bulky for tactical and range use but the only want to go for hardcore USPSA Carry Optics and Production shooters.

If you’re a more casual competitor of looking for a solid tactical option when not wearing Armor I would suggest using something like an X Lock or a Tech Lok. These types of mounts allow you to attach you Sig P320 X5 Legion OWB Holster to the belt and take them off without any tools. It will likely take you 30 seconds to a minute to do so but it doesn’t require you to take the belt off or unthread any other items you may have on the belt. These slide locks work with belts ranging from 1 inch all the way up to 2 inches using a bar system that adjusts in quarter-inch increments.

If you have your belt setup for tactical use with universal magazine pouches and you like to be able to switch out to different guns and holsters on the fly then you’ll want to check out the Safariland QLS(Quick Locking System). The Safariland QLS mounts a fork to your Sig P320 X5 Legion holster and then you mount the female adapter to your belt. Just bay pinching in the tongs on the fork you can take the OWB Holster off of the belt and replace it with a Sig P320X 5 Light bearing holster or any other holster of your choice.

For light using on the range or around the house, you can use a Sig P320 X5 Paddle holsters. By adding a paddle to your holster you can then put the holster on and take it off very quickly. This is a great option for those that want an easy-to-use holster that they won’t be wearing all day and need convenience.

Despite its heavyweight there are many people that choose to carry the Sig P320 X5 Legion in an IWB holster. With the right Sig P320 X5 Legion IWB holster and a reasonable loose cover garment, you won’t have any issues concealing the gun but the weight is something to think about. If you’re carrying the gun all day long it could have long-term negative health effects on your joints. While the weight of the gun may not seem like much when carrying it in a good Sig P320 X5 Legion IWIB Holster you’ll still have potential long term negative health effects that you should consider. The slight performance you could gain in a gun flight might be outweighed by the damage it could do to your long-term mobility.

Features

The Sig P320 X5 Legion is a massive gun weighing in at 43.5 ozs. It uses a polymer frame that is infused with tungsten to increase the weight multiple times over what a normal Sig P320 X5 frame would weigh. Sig’s theory behind this I’m sure was partially motivated by injection molded frames being cheaper to produce than machined frames. If you’ve spent any time shooting both heavy steel-framed guns and polymer-framed pistols you know that the weight of the steel does help with recoil but it also transfers more shock to your hand while the polymer frame absorbs some of the shock from the recoil. Sig theory was that the combination of heavy tungsten combined with polymer would give you the best of both worlds.

The gun holds 17 rounds and the magazine ship with henning group aluminum base pads. The gun will take any Sig P320 magazine that is compatible with the Sig X Frame. If you plan to shoot USPSA in a division that requires your magazines fit within their 140mm guidelines note that sig’s 21round magazine for the Sig P320 might not fit with the USPSA certified gauge. Some of the 21 round magazines do and others have done and this is why I suspect Sig ships the P320 X Legion magazine with the henning group base pads. The aluminum base pads do give the entire package a higher-end feel.

One thing you’ll notice right off the bat is the massive magwell on the bottom of the gun. The magwell is removable and not part of the frame in case you need to remove weight from the gun or the sport your shooting that allows magazine wells that aren’t part of the frame. The Sig P320 X5 Legion magwell is extremely effective meaning you don’t have to be good at reloading to get good times on the clock with the magwell installed. USPSA Carry Optics division requires you to take the Sig P320 X5 Legion magwell off of the gun to compete. Without the magazine well mounted the Sig P320 X5 Legion is typical of pretty much any similar-sized gun and offers you no advantage on the reload. This is one area the Gen 5 Glock has a clear advantage over the Sig X5 series. The Glock has a large flare built into its mag well and it’s part of the frame so it fits within USPSA guidelines.

Grip/Ergonomics

reallyThe grip on the Sig P320 X5 legion is absolutely massive so it allows you to get a really good grip on the gun if you have medium to larger sized hands. There are no backstraps or other means of adjusting the frame size and ergonomics to the shooter. The grip isn’t exactly the most comfortable in the hand but it allows you to place force in all the right places on the gun to effectively control recoil. If you’re looking for the most comfortable grip then you might want to reconsider the Sig P320 X5 Legion and go with the standard Sig P320 Frame.

If you have massive hands the grip on the P320 legion might be a little short for your hands if you don’t have the magwell installed. Even though the P320 holds 17 rounds with a flush fit magazine the grip is slightly shorter than say a Glock 17 Gen 5. The reason for this is the Sig P320 series has a reliability high bore axis and that high bore axis and the location of the P320 chassis push the bottom of the trigger guard undercut lower which means you don’t have quite as much real estate for your fingers on the grip. But like I said unless you have massive hands the Sig P320 X5 Legion grip should fit you fine.

The texturing on the gun isn’t crazy aggressive but it isn’t slick either. The Sig P320 tungsten frame has a slightly abrasive texture even in areas that don’t have texture. The legion frame feels like it’s made of very hard chalk. There is matching molded-in texturing on the front strap, back strap, and the slides and it’s very effective at keeping your hand in the same place on the gun. If you’re carrying this gun IWB it might be a little bit aggressive on the skin. The Texturing feels more durable in a Tungsten polymer hybrid frame than it would in a normal polymer frame.

 

The slide is absolutely huge and while the serrations aren’t crazy aggressive they certainly get the job done. The coating they have on the slide also has that chalky feel which further helps you get traction when tracking the slide. The slides have a significant chamfer that gets even larger as you get more forward on the side. Their serrations on the front of the slide are only locations on the sides and to not extend up to the chamfers but they’re still easy to grab when racking the slide from the front or conducting a press check. There are lightening cuts on the top of the slide but they don’t affect your ability to manipulate the slide in any way.

Sights

The Sig P320 legion has a Dawson precision adjustable rear-mounted on the optics mount cover pate. They’re matched with a green fiber optic front and example what you would expect to find on a gun design for competition shooting. If you plan to run a red dot you’ll lose full use of your rear sight since it’s mounted to the plate instead of a dovetail milled into the slide.

The current production P320 Legion is compatible with Sig’s Romeo1Pro optic. The original Sig P320 X5 used a propriety mounting system that matched with the Sig Romeo 1 they produced at the time and then they moved to the Leupold Delta Point Pro Pattern after the M17 was adopted. The Sig P320 X5 legion was originally introduced with the delta point pro mounting pattern but it was later changed to the new pattern Sig pattern developed for the Sig Romeo1Pro.

Controls

The magazine release on the Sig P320 X5 Legion will require most people to break their grips to drop the magazine. You can reverse the magazine release to the other side of the tungsten frame if you’re left-handed. I have average-sized hands for a 6’ tall male and I have to slightly break my grip to drop the magazine so keep that in might if you have really small hands.

The slide releases are ambidextrous and they might be the smoothest slides release I’ve ever felt form either side of the gun. On most guns, with ambidextrous slide releases, it’s significantly easier to drop the magazine release on the if you’re right-handed than it is if you’re a lefty and this holds true on the Sig P320 X5 Legion as well. They are easily reached without having to break your grip. The slides releases don’t’ stick out far from the slide but they are angled perfectly so your thumb applies maxim pressure with pressing down. They’re also really easy to push up from the bottom if you want to lock back the slide. One thing I will say about the legion is the slide seems to drop easier than most other guns. I think the uniquely smooth action of the Sig P320 Legion slide plays a large role.

Overall Ergonomics

The overall ergonomics of the Sig P320 X5 Legion are very good but you may struggle with them if you have medium to smaller hands. The texturing is a pretty nice sweet spot in that it’ll likely work for both the casual shooter who doesn’t want to tear up their hands and the hardcore shooter with heavily calloused hands.

Trigger

The gun uses a skeletonized flat trigger that feels good on the pad of my finger but the corners of the face of the trigger are quite sharp so if you have smaller or larger hands than mine the Siig P320 X5 Legion trigger might not be for you. There are plenty of aftermarket trigger shoe options for the Sig P320 that we’ll go over later.

As far as the characteristics of the actual trigger pull there is light takeup and then you reach a nondefinite wall and then some creep before the trigger breaks. The only way I can describe the trigger breaking is creepy with somewhat of a rolling break. The reset is light and springy and there is an audible reset that you can feel and then some creep before the trigger breaks again. As far as striker-fired triggers go it isn’t bad but it’s not exactly good either. It’s a relatively light trigger which somewhat saves it till I remember the price tag of the gun and that it’s parts of Sig’s high-end legion line. This trigger doesn’t belong in the legion it’s like having a very well-performing 4 cylinder engine in a Mercedes AMG or a BMW M series vehicle. Yes, it does okay but it doesn’t quite live up to the name as you’d expect.

Maintenance

Maintenance on the Sig P320 series is a little hard for field stripping that a Glock but the fire control group is much easier to work on. And the ability to take it out of the frame in one piece is a major advantage over all the other common striker-fired designs on the market. The X5 Legion also uses the non captured recoil spring from a 5 inch 1911 so you have lots of options for turning your gun to your preferences and favorite 9mm load.

Aesthetics

Rugged with a little bit of refinement is the way I would describe the looks of the Sig P320 X5 Legion and most of the refinement comes from the competition style sights. Overall it looks more like a battle gun than a competition gun. It has more of a tactical look but I like it!

Shooting

When you pull back the slide to load the first round into the Sig P320 X5 Legion you realize this is much different than your typical striker-fired competition gun. It has a smooth feel to it that I suspect is from the steel guide rod and 1911 recoil spring. The slide movement feels like an odd cross between a high end 1911 and your average $500 striker gun.

Once you start shooting the gun you realize the heavy tungsten frame does affect the recoil impulse but you start to call BS on Sig’s theory that the tungsten polymer hybrid frame has the flex of polymer but the weight of steel. The gun doesn’t move quite as much as the polymer-framed Sig P320 X5 but it doesn’t have the same recoil absorption as a normal polymer frame. The tungsten really stiffens up the Sig P320 X5 Legion frame so it doesn’t absorb as much recoil as you would hope.
