The Mec-Gar 15rd 9mm Luger magazine for Sig P229/P228 pistols delivers genuine capacity without the bulk. Built on a patented design (US Patent# 5386657), this flush-fit magazine squeezes two extra rounds into a frame that matches your gun's original footprint—no printing, no snag, no compromise. Whether you're running drills at the range, carrying daily, or training hard, these 15-round magazines let you stay in the fight longer without changing how your P228 or older P229 sits in your hand or holster.
Mec-Gar USA has been the OEM supplier for Sig and other major manufacturers for decades, and this magazine shows it. The carbon steel tube is heat-treated for durability under real use, paired with a high-tensile music wire spring that resists degradation over thousands of cycles. The polymer follower rides smoothly, and the removable steel butt-plate makes cleaning and maintenance straightforward. This is working gear, not a novelty—it's designed to run.
Important compatibility note: this magazine is designed for the P228 and earlier, flat-sided P229 models. It will not work in the P229 E2 or any P229 variant that uses the wider, tapered P229-1 magazine. Check your pistol's specs before ordering to ensure fit. Once you've verified compatibility, you're getting genuine Mec-Gar quality at a price that makes stocking spares practical.

Frequently Asked Questions
Will this magazine fit my Sig P229 E2?
No. This magazine is designed for the P228 and older, flat-sided P229 models only. The P229 E2 uses the wider, tapered P229-1 magazine and is not compatible with this flush-fit design. Verify your pistol's configuration before purchasing.
Can I use this 15-round magazine in my P228?
Yes. This magazine is engineered for both the P228 and the earlier P229 with flat-sided, narrow magazine profiles. Check that your P228 accepts the flat-sided magazine design to ensure compatibility.
How is Mec-Gar able to fit 15 rounds in a flush-fit magazine?
The design incorporates a patented innovation (US Patent# 5386657) that adds two rounds beyond the standard capacity without increasing the magazine's overall dimensions, allowing the magazine to sit flush with the grip while holding more ammunition.
What makes Mec-Gar magazines reliable?
Mec-Gar magazines use heat-treated carbon steel tubes and high-tensile music wire springs, the same materials and processes used in OEM production. The polymer follower ensures smooth feeding, and the removable steel butt-plate allows you to maintain the magazine easily.
