This Mec-Gar 15-round magazine is purpose-built for the SIG P228 and older P229 models with flat-sided narrow magazine wells. It adds two rounds over the factory 13-round capacity while remaining flush-fit with your pistol, so you get significantly more firepower without compromising the compact package that makes the P228 so practical for carry.
The mag is constructed from heat-treated carbon steel tube with a high tensile music wire spring and high-impact polymer follower. Mec-Gar manufactures the original OEM magazines for SIG and other major firearm brands, so these operate to the same exacting standards that professionals rely on. The blued finish resists corrosion while providing a clean look that matches your pistol.
From the factory, the spring may feel stiff until broken in, which is normal and actually ensures proper retention and feeding. Once cycled a few times, it feeds smoothly in all shooting scenarios whether you're at the range or in a duty environment. The numbered witness holes on the side let you quickly check your round count without opening the mag. The polymer baseplate sits flush with the grip, maintaining the profile you want.
Note: This is specifically designed for the P228 and pre-E2 P229 models. It will not work with the newer P229 E2 pistols that use the wider tapered P229-1 magazine. If you need maximum capacity with your P228, larger Mec-Gar magazines designed for the P226 will also work but will extend noticeably past the grip.
It depends on which P229 you have. This magazine works in the P228 and older P229 models with flat-sided narrow magazine wells. However, it will not fit the newer P229 E2 (P229-1) pistols, which have wider tapered magazines. If you're unsure which P229 you own, check with the manufacturer or a SIG armorer to confirm compatibility.
Mec-Gar engineered these with a shorter polymer follower and optimized spring design that allows the extra rounds to stack without extending the baseplate. The result is two additional rounds of capacity while maintaining the compact profile your P228 is known for, no magazine pouch extension needed.
Yes, new magazines often come with stiff springs, which is by design. The tight spring tension ensures proper retention and reliable feeding. After a few loading cycles, the spring will loosen up and feel more natural. This is completely normal and actually a sign of quality.
Mec-Gar is an Italian manufacturer that has been producing magazines since 1965. They're the original OEM supplier of magazines for SIG Sauer and other major firearm brands, so these operate to military and law enforcement standards.
Yes, P226 magazines will function in a P228, but they extend about a half-inch past the grip, affecting concealment and how the pistol fits in holsters. If you want more capacity without the extension, the Mec-Gar 15-round P228-specific magazine is the better choice.
Mec-Gar stands behind their magazines as quality products engineered to strict tolerances. While specific warranty terms depend on the retailer, these are built to last thousands of rounds and are trusted by competitive shooters, law enforcement, and military users worldwide.
