Sig Sauer P320x5 Legion: Quick Take

The Sig Sauer P320x5 is one of the best off the shelf pistols money can buy. Dollar for dollar you aren’t likely to find a better pistol, unless of course, you consider the brand new Sig Sauer P320x5 Legion which promises a whole host of changes. This article is going to be an aggregation of the most relevant articles and videos available on this new Legion Pistol.

Sig Sauer P320x5 Legion Key Points

If you read nothing else in this review then check out these key points which we will cover in much more depth below.


  1. Increased Weight to 43.5 oz
  2. 50% Less Recoil
  3. Reduced Trigger Weight and Travel
  4. Red Dot Optic Compatibility Out of the Box
  5. 1911 Style Guide Rod

Sig Sauer P320x5 Legion Weight

This is bar far the biggest headline with this new pistol. The wizards that Sig Sauer employ have managed to infuse the polymer grip with tungsten to bring the frame weight up to that of many steel guns. This does several things for the shooter.

It lowers muzzle flip, and decreases felt recoil. You can actually see a side by side recoil comparison between the old P320x5 and the Legion towards the end of the video above.

Sig also claims because the grip is still polymer that you get some frame flex which also contributes to less felt recoil. Personally, I don’t know if I’m a good enough shooter to notice that, but it’s a pretty good marketing line.

Sig Sauer P320x5 Legion Recoil Reduction

This increase in weight is really targeted at USPSA and other practical pistol shooting sports. Any reduction in muzzle flip and recoil has a huge impact on your ability to track your sights during the recoil cycle, making follow on shots, and calling your shots much easier.

This also makes the gun much more newbie friendly. In my experience, new shooters almost always fear the noise and the perceived recoil in equal parts.

We can’t do anything to get rid of the noise without using a suppressor, but we can reduce the felt recoil, making it much more comfortable to shoot for those new to shooting sports.

Sig Sauer P320x5 Legion Reduced Trigger Weight and Travel

This is one area that you never know you really want until you try a gun with a really nice trigger, and then you are ruined for normal triggers for ever after.

I like that they have listened to the industry, taking in a variety of viewpoints, and have decided to lower the pull weight, as well as shorten the overall travel and reset.

Check out this video where you can see the trigger in action.

This is much more slanted towards competition shooters, but anyone can appreciate a nice trigger. I really like that you don’t have to buy an already expensive gun and then spend hundreds more on a gunsmith to fine tune your trigger.

This is also going to give you a more reliable weapon. In my mind any time you modify a gun from stock you will affect reliability. The gun simply wasn’t designed that way, and contrary to popular belief most folks aren’t engineers.

Thats not to say that you shouldn’t modify your pistol at all, but if reliability matters to you, then the less modification the better.

Sig Sauer P320x5 Legion Optic Compatibility

This gun is meant to compete very strongly in the USPSA Carry Optics division which allows a slide mounted red dot sight. You have two options here that will fit the slide directly from the factory.

You can mount Sig Sauer Romeo Reflex Sight, or you can mount the excellent Leupold Delta Point Precision Pro. Personally, I have no experience with Sig Sauer Optics, but many folks swear by them.

I will say that in our review of red dot sights for pistols, the Leupold came out as one of the few optics that Sage Dynamics recommended as durable enough for duty use. Their study was very in depth, lasting years, and I would feel confident mounting one of these optics based off of that.

If you have the luxury of trying both, then I would definitely try them as they have a few differences that might sway you either way. It should also be noted that you can mount adapter plates to the slide allowing for nearly any optic to be mounted with minimal effort.

Sig Sauer P320x5 Legion 1911 Style Guide Rod

This is probably the least useful update to the Sig 320×5 Legion. If you are a die hard tinkerer then you will like this update. This effectively allows you to choose any 1911 recoil spring and use it in this pistol.

Many competition shooters, especially those that hand load their ammunition, will match their loads with a certain weight spring to achieve a little softer recoil.

This isn’t going to be a huge difference, but if you are a very competitive shooter, or you just like tinkering, this update will give you hours of fun or frustration, depending on your mood.

Sig Sauer P320x5 1911 Final Thoughts

This gun is the best deal you can get for the money. It is currently listed at Sportsmans Outdoor Superstore for a pre order price of $899. It comes with three 17 or 10 round magazines depending on what kind of state you live in, and those mags already have some sick Henning Base Pads.

In my mind if you want one gun that will allow you to shoot in multiple USPSA categories and not be held back, then this is your gun. You can shoot Limited right out of the box, and production with the magwell removed. You can also run it in Carry Optics with the addition of a reflex sight.

The real clincher for me is that this package would be ready to go right from the store, requiring no tuning or updating. I’m not a tinkerer, and I place a high premium on things that work all the time, and the Sig P320x5 Legion seems like it checks all those boxes.

Stay tuned for more info on this sweet gun, as more quality reviews come out I will keep you posted.
