Mec-Gar Sig Sauer P226 9mm 18-Round Magazine w/ Anti-Friction Coating - MGP22618AFC - UPC 765595515000

Product Description

The Mec-Gar Sig Sauer P226 9mm 18-Round Magazine (MGP22618AFC) is a premium, high-capacity flush-fit feed source engineered specifically for the full-size Sig Sauer P226 9mm pistol platform. Utilizing Mec-Gar’s proprietary redesigned feed geometry and internal spring system, this magazine provides a +3 round capacity boost over standard factory 15-round magazines—all while maintaining a clean, flush-fit profile against the bottom of the grip frame.

Constructed from heat-treated carbon steel, the MGP22618AFC features Mec-Gar’s signature Anti-Friction Coating (AFC). This specialized surface treatment drastically reduces internal friction for ultra-smooth cartridge feeding, shields against extreme salt-spray corrosion, and allows carbon fouling, sand, and dust to wipe off easily. The self-lubricating properties of the AFC finish also ensure slick, drop-free magazine ejection under severe operational conditions.

Equipped with an anti-tilt high-impact polymer follower, high-tensile music wire spring, and a high-impact polymer floorplate, the MGP22618AFC guarantees reliable round presentation and lockback. Trusted worldwide as an original equipment manufacturer (OEM) for elite firearm producers, Mec-Gar delivers unmatched durability, capacity, and feeding performance for duty, tactical, and personal protection applications.

*Armorer Bench Notes & Real-World Staging Guidance:

Fitment Matrix: Direct fit for full-size Sig Sauer P226 9mm pistols (including P226 Legion, MK25, P226 Nitron, and DA/SA / DAO variants). Note: Will NOT fit compact P228/P229 models or single-stack P225 pistols. Compatible with aftermarket flared magwells that accept flush-fit basepads.

1. Verify the firearm is completely clear, safe, and unloaded before testing magazine insertion or drop-free release.
2. Load 9mm cartridges straight down onto the follower to ensure complete rear-rim seating against the magazine spine.
3. Periodically remove the floorplate assembly to clean out range dust and carbon residue using a dry magazine brush—do not lubricate the inner tube wall with heavy liquid oils, as the AFC coating is naturally self-lubricating.
