Sig P320 X5 LEGION - The Ultimate Build
This video details a custom build of a Sig P320 X5 Legion, focusing on creating a "flat-shooting" competition pistol. The build starts with an 80% P320 module (MUP-1) and incorporates a Norsso slide, Parker Mountain Machine (PMM) barrel and compensator, a tungsten-infused SIG XFIVE Legion grip module, an Apex Tactical trigger bar, and a DPM Systems recoil reduction system. The content covers the complete assembly process, a close look at each part, the 80% build, and a function check, aiming to determine if a custom build is superior to a factory model.
