Description
The Sig Sauer P226 MK25 CA Compliant exists because California buyers should not be shut out of a design the US Navy spent a decade validating. MAG5 Firearms stocks this configuration with the anchor engraved on the slide, a 4.4-inch barrel, an aluminum frame with a Picatinny rail and a ten-round magazine.
The Pistol Behind the Anchor
The MK25 designation traces to a Navy contract that demanded a sidearm capable of running after saltwater immersion, sand and mud, across round counts that end most service pistols. The P226 met it and stayed in service for decades.
The Sig Sauer P226 MK25 CA Compliant carries the same corrosion-resistant treatments and phosphated internals the contract specified. This is the actual pistol, built to a state-specific configuration, not a commemorative with a logo added.
Hammer-Fired Operation and the Decocker
A long double-action first press resists accidental discharge, and every shot afterward breaks short and clean in single action. No manual safety needs disengaging under pressure.
The decocking lever lowers the hammer without touching the trigger, so the Sig Sauer P226 MK25 CA Compliant goes back in the holster loaded but uncocked. That sequence is the reason this manual of arms outlasted its critics.

Compliance and What It Does Not Change
This configuration is built to satisfy California requirements, and the difference is the magazine capacity rather than the gun. Frame, slide, barrel and trigger are the same parts found in the standard MK25.
Requirements vary by state and sometimes by county, so confirm with your receiving FFL before ordering. Compliance lists change independently of federal law.
Sig Sauer P226 MK25 CA Compliant Construction and Shooting
A hardcoat anodized aluminum frame and a Nitron stainless slide give this pistol the weight to turn 9mm recoil into a mild push, which is why full-size P226s are still the gun of choice for high-round-count training.
A Picatinny rail takes a weapon light, and the beavertail lets the hand ride high over a low bore axis so the muzzle stays flatter than the size of the gun suggests.

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.
