Description
The Sig Sauer P365X MA Compliant puts the twelve-round X-grip carry pistol on the shelf in a state where most modern handguns are unavailable. MAG5 Firearms stocks it with a 3.1-inch barrel, a manual thumb safety, a factory optic cut and ten-round magazines in the box.
Sig Sauer P365X MA Compliant and What Compliance Changes
The barrel, slide, frame, trigger and grip module are the same parts found in the standard P365X. The magazines that ship with it are the difference, and the magazine well is unchanged.
Compliance lists change independently of federal law, so confirm current requirements with your receiving FFL before ordering.
The X Grip and the Manual Safety
The P365X keeps the short 3.1-inch slide but uses the longer XSeries grip module, so most hands get a full three-finger hold rather than curling a pinky under.
A thumb safety gives a positive mechanical block, which for appendix or bag carry is often what makes carrying acceptable at all. On the Sig Sauer P365X MA Compliant the lever sits low enough that it does not catch clothing.

Optic Cut and Sights
The slide is cut for the SIG-LOC compact footprint, which mounts a compatible optic directly to the slide with no adapter plate. Plates are the most common failure point in a pistol optic setup.
On a 3.1-inch barrel the sight radius is short enough that a dot produces a real accuracy gain rather than a marginal one, and the advantage widens in low light.
Carry, Rail and Holsters
An accessory rail on the dust cover takes a compact weapon light, which turns the Sig Sauer P365X MA Compliant into a credible home defense pistol when it is not on the belt.
Holster support for this frame is as broad as it gets, including kydex cut for optics and light-bearing setups.
