Sig Sauer P320 X-Five Legion Combo


In stock


The Legion P320 X-Five Legion Combo Kit at JSD Supply is one of the best Sig Sauer compatible kits on the market. You’ll build your new firearm with only a few tools by following straightforward instructions. Or you can upgrade your current MUP-1 or Sig Sauer P320 to the new X Five Legion build. The X Five Legion is the most race ready parts kit you can buy for the p320 platform. A tungsten infused grip module is the perfect combination of polymer and metal. It adds enough heft to reduce felt recoil, while staying modular. For a range or competition gun, this is my absolute favorite build.

  • Dawson Precision Fiber Optic Front Sight
