The P365XL isn’t the only new product from SIG. They’re also releasing a P320 X5 Legion. It looks a lot like their regular P320 X5, with the Xgrip, slide with lightening holes, bull barrel, and removable rear sight plate to accommodate optics.
The P320 X5 Legion has a new flat trigger design, which is skeletonized. I think this is mostly just to look cool.
More importantly, SIG has added weight to the gun. They’ve infused the grip with tungsten, bringing the weight up to 43.5 ounces. More weight in the grip will make the pistol more controllable in recoil, and should provide good competition to the Walther Q5 SF. If you like heavy pistols, you are getting some options.
The P320 X5 Legion comes with three magazines with aluminum basepads. Osage County Guns has a product page with a buy now price of $929, though no word yet on when you’ll be able to get it.
