Description
The Sig Sauer P320 XFive STAS is a striker-fired pistol built around a stainless steel grip frame, which is the closest thing the P320 line has to an all-metal competition gun. MAG5 Firearms stocks it with a 5-inch barrel, a bead-blasted slide and LOK G10 grip panels.
The Stainless Grip Frame
Replacing the polymer module with machined stainless puts real weight low in the hand. Lowering the center of gravity stops the pistol rotating under recoil far more effectively than anything done above the trigger.
The result on the Sig Sauer P320 XFive STAS is a gun that tracks like a steel-framed pistol, because functionally it is one, while keeping the P320 trigger and fire control unit.
Bead Blasted Finish and Five Inch Barrel
Bead blasting gives the stainless slide a soft matte sheen that cuts glare on a bright range and hides handling marks far better than a polished finish.
At five inches the Sig Sauer P320 XFive STAS has the longest sight radius in the P320 family, which reduces the angular error a shooter contributes on every shot.

LOK G10 Grip Panels
LOK panels are what a lot of competitors install on their own pistols. The texture locks the hand in place through a long stage without abrading a cover garment, and G10 holds that texture for years.
On a gun this heavy, grip security matters more than it does on a light polymer pistol, because there is more mass to control under recoil.
Sig Sauer P320 XFive STAS Optic Cut and Rail
The slide arrives cut for a red dot, so an optic mounts directly with no plate and no gunsmithing. Given how flat this pistol tracks, a dot stays in the window through an entire string.
A Picatinny rail is present as well, which is unusual on a dedicated competition pistol and makes this one more versatile than a pure race gun.
