It’s been almost a year since Sig Sauer introduced the Legion series of their popular X FIVE pistol. And it continues to impress. Sig made several improvements to an already impressive pistol and the result is very impressive.
The X Five Legion’s main selling point is the tungsten infused grip module. By adding tungsten during the molding process Sig was able to raise the weight of the pistol to 43.5 ounces with an unloaded magazine. The heavier pistol helps soak up felt recoil which makes the pistol faster and easier to shoot. Sig was careful to add enough weight to dramatically enhance the shooting experience, and still adhere to the equipment rules of some of the most popular shooting sports.
Another big change Sig made with the Legion series was the slide design. Sig changed their optics cut to match the footprint for the Sig Sauer Romeo 1 Pro, which shares a footprint with the Leupold Delta Point Pro. Either of these optics will interface directly with the slide cuts on the Legion. If you would like to use a different red dot you will have to source a mounting plate from an outside manufacturer. 
Sig also updated the sight plate on the Legion. The new plate has a rear sight that is adjustable for both windage and elevation. They also stamped the Legion logo on the sight plate.
The next notable change is the trigger. Sig skeletonized the trigger on the X Five Legion and advertises that it comes in up to 30% lighter than the original trigger. My tests indicated that on average, the Legion is 7 ounces lighter than the standard variation of the X trigger. The trigger feels very good for a stock trigger in a striker fired pistol.
Sig changed up the barrel of the X Five Legion slightly by adding a loaded chamber indicator. Sig accomplished this by cutting a small window in the barrel hood that allows the shooter to see brass when a round is the chamber. The downside is the port allows gas to blow back directly on the glass of the optic.
Next Sig changed the recoil rod and spring assembly for the Legion series X Five. Sig went with a one-piece solid steel guide rod and a 12 pound 1911 style spring. Sig went a step further and included an extra 14 pound recoil spring as well. This allows the shooter to tune the pistol to their ammunition choices and shooting styles.
The last major change between the X Five and the Legion series are the magazines. The X Five Legion has three 17 round magazines included. The magazines feature textured, aluminum base plates provided by Henning Group that have the Legion logo stamped on them.
This impressive list of features makes for an excellent pistol out of the box. At a retail price of $900 it seems like Sig has struck gold. If you are looking for a new pistol this should absolutely be on your list.
