Description
The Sig Sauer P320 SXG Max 10 Round exists so a magazine limit does not push a competitor down to a lesser pistol. Everything that makes the SXG worth owning is here unchanged: the stainless grip frame, the 5-inch match bull barrel, the Hogue aluminum panels and a ROMEO3 MAX already mounted.
Sig Sauer P320 SXG Max 10 Round Compliance Without Compromise
The barrel, slide, grip frame, trigger and optic are identical to the standard-capacity gun. Only the magazines in the box differ, and the magazine well is unchanged.
Verify your own state and local rules before ordering, since compliance lists change independently of federal law.
The Stainless Grip Frame
SXG stands for stainless grip, and the weight it adds sits low in the hand where it matters. Lowering the center of gravity stops the pistol rotating under recoil far more effectively than any change to the slide.
That makes the Sig Sauer P320 SXG Max 10 Round a striker-fired pistol that tracks like a steel-framed competition gun, because functionally that is what it is.

Match Grade Bull Barrel and Sight Radius
A bull barrel carries mass at the muzzle where it damps rise, and the thicker profile resists the whip thinner contours develop through a long string of fire.
At five inches the Sig Sauer P320 SXG Max 10 Round has the longest sight radius in the P320 family, and match-grade tolerances tighten groups against the same ammunition a service barrel would shoot.
The Included ROMEO3 MAX
A 6 MOA dot is deliberately large. On a competition gun the priority is finding the dot instantly on the draw and on transitions rather than shooting tiny groups at distance.
Because the optic ships mounted, there is no footprint research, no plate to order and no discovering later that the irons no longer line up.

Ownership Tips
Before your first range trip, read the owner’s manual and practice loading, unloading, and field-stripping with an empty gun. Clean and lightly lubricate the pistol after each session, paying attention to the slide rails, barrel hood, and breech face, and use quality gun oil sparingly. Inspect magazines for dirt and weak springs, and replace springs on a regular schedule if you carry the gun daily.
For carry or home defense, test the ammunition you plan to rely on with at least a few boxes to confirm reliable feeding. A quality holster that covers the trigger guard, a sturdy belt, and a weapon light round out a dependable setup. Check your state and local rules on magazine capacity and transport before ordering, and we will ship to the licensed dealer of your choice.
