The legion is the fifth 10mm in my collection and by far my favorite to shoot. The all stainless steel construction of the legion tames the hottest 10mm round. I put two hundred rounds of sig elite performance fmj, Underwood 165 grain bonded jhp, and Buffalo Bore heavy 180jhp through the Sig on my first trip to the range with it. No issues what so ever the Sig preformed flawlessly. The sights are some of the best on the market. Very similar to trijicon hds, but the green front on the X-ray sights are easier to pick up in different lighting conditions. The controls are more ergonomic and fit closer to the frame then your average Sig P220. The recoil spring and guide rod are all steel one piece captive on this model. The spring weight is around 22-24 pounds. The finished is tough and came flawless out of the box. The gun carry’s very well depending on your belt and holster choice. Carry’s very similar to the older Sig 220 45s in all Stainless Steel. The one down side to the firearm is finding holsters for it if you don’t know where to look. Tucker Gun Leather and Double Diamond make great holsters for the firearm as do several custom kydex makers. Overall if your looking for a 10mm pistol that’s built like a tank, loaded with features, and is built to handle the hottest 10mm loads look no further. This firearm is a little pricey but for what you’re getting in my opinion the Legion is worth it.
