Mec-Gar SIG P228 9mm 15-Round Magazine
The Mec-Gar MGP22815B is a 15-round flush-fit 9mm magazine built for the SIG SAUER P228 and older flat-sided P229 pistols. It pairs a heat-treated carbon steel tube and blued corrosion-resistant finish with a high-tensile music wire spring, high-impact polymer follower, and flush polymer floorplate for dependable feeding round after round. Capacity runs two over the factory SIG mag while staying flush with the frame, so you gain rounds without adding length. Manufactured in Italy by Mec-Gar — the same OEM that supplies SIG SAUER — this magazine is a dependable upgrade for duty, range, and concealed carry use. Note: not compatible with the P229-1 or P229 E2 with tapered magazine well.

Works great for my P228 CarryLoaded this up for my P228 and took it to the range last weekend for some drills. It fits flush and gave me those extra rounds without changing the grip feel at all. The spring was stiff right out of the box and took a bit to get all 15 in there. Works great once broken in though.

Feeds reliably after break inStiff spring when new
