Description
The P228 is one of those pistols that people hold onto for good reason, and if you need spare magazines for yours, Mec-Gar is the right call. They've been the OEM supplier behind many Sig Sauer-branded magazines for years, so buying directly from Mec-Gar is essentially getting the same product without the Sig logo markup.
This particular magazine holds 15 rounds of 9mm and does it flush, meaning no basepad extension hanging out the bottom of the grip. The factory P228 magazine ships with 13 rounds, so the Mec-Gar MGP22815N adds two more through a patented redesign that squeezes additional capacity into the same footprint. The tube is heat-treated carbon steel, the spring is high tensile music wire, and the follower and floor plate are both high-impact polymer. The nickel finish adds a layer of corrosion resistance and gives the magazine a clean look that pairs well with nickel or stainless pistols.
Fit compatibility is worth knowing before you order. This magazine is designed for the P228 and older P229 pistols with the flat-sided narrow magazine tube. It does not fit the P229 E2 or P229-1 models, which use a wider, tapered magazine with a different body profile. If your P229 originally shipped with a 13-round magazine, you're most likely in the flat-sided camp and this will fit. If it came with a 15-round flush-fit from the factory, you likely have a P229-1 and will need a different magazine.
At the range or kept as a spare, this mag is a solid upgrade over carrying a single factory magazine. The build quality is consistent with what Mec-Gar supplies to military and law enforcement customers worldwide, and the feedback from P228 owners who've run these through extensive shooting bears that out. One magazine is included per package.

Frequently Asked Questions
Will the Mec-Gar MGP22815N fit my Sig P229?
It depends on which version of the P229 you have. This magazine fits the older P229 models that came with a 13-round, flat-sided narrow magazine. If your P229 is the E2 or P229-1 variant, it uses a wider tapered magazine body and this one will not fit. A quick way to tell: if your gun originally shipped with a 13-round magazine, this Mec-Gar will almost certainly work.
Does the Mec-Gar 15rd magazine stick out the bottom of the P228 grip?
No. This is a flush-fit design, meaning the floor plate sits flush with the bottom of the grip frame just like the factory magazine would. Mec-Gar achieves the extra two rounds of capacity through a patented internal redesign rather than adding a basepad extension, so the overall dimensions of the magazine stay the same.
Is Mec-Gar a reliable brand, or is this an off-brand replacement?
Mec-Gar is about as far from off-brand as you can get. They are the actual OEM manufacturer behind many of the Sig Sauer-branded magazines that have shipped with Sig pistols for years. The company has been manufacturing magazines in Italy since 1965 and supplies militaries and law enforcement agencies worldwide. Buying the Mec-Gar-branded version is essentially the same product as the Sig-boxed version.
How does the 15-round capacity compare to the factory P228 magazine?
The stock P228 magazine holds 13 rounds. The Mec-Gar MGP22815N gives you two additional rounds of 9mm in the same flush-fit package. That capacity bump is made possible by a patented tube redesign that optimizes the internal geometry without changing the external footprint of the magazine.
Is the nickel finish just cosmetic, or does it serve a function?
Both. The nickel plating on the steel tube does add a meaningful layer of corrosion resistance compared to a blued finish, which matters if the magazine sees sweat, humidity, or less-than-ideal storage conditions. It also makes the magazine easier to clean and wipe down. If you have a nickel or stainless pistol, it's a natural visual match too.
Can I use this magazine for carry, or is it just a range magazine?
Mec-Gar builds this magazine to the same quality standards they supply for duty and military use, so it's perfectly suitable for carry as a spare. The heat-treated steel body, music wire spring, and polymer follower combination is designed for reliable feeding under real-world conditions. Many P228 owners run these as both primary and backup carry magazines with no issues.
