Checkmate Sig P226 18-Round Magazine

Features

1. 18-Round 9mm Capacity — Holds 18 rounds of 9x19mm in a flush-fit body, giving you two extra rounds over standard 15-round P226 magazines without an extended baseplate.
2. Flush-Fit Design — Sits clean against the magwell for unobstructed grip, comfortable carry, and snag-free reloads from a belt or pouch.
3. Heat-Treated Steel Body — Carbon steel tube is heat-treated and finished for corrosion resistance and long service life under heavy range use.
4. High-Tensile Steel Spring — Heavy-duty spring maintains consistent feed pressure from the first round to the last, even after extended loaded storage.
5. Polymer Follower — Anti-tilt polymer follower keeps rounds properly aligned and reliably engages the slide stop on the last shot.
6. Removable Floor Plate — Detachable baseplate allows quick disassembly for cleaning, inspection, and spring replacement.
7. SIG P226 Compatibility — Drops into full-size SIG Sauer P226 9mm pistols, including legacy, E2, and current production variants.
8. ISO 9001 Manufacturing — Built by Check-Mate Industries, a US-based ISO 9001-certified OEM supplier with decades of military and law enforcement magazine experience.
9. Precision Feed Lips — Tightly controlled feed lip geometry delivers a wobble-free fit in the magwell and consistent presentation to the chamber.
