The Mec-Gar Plus 1 Conversion Kit is a straightforward upgrade that boosts your Mec-Gar P226 18-round magazine capacity to 19 rounds. This kit works specifically with Mec-Gar brand 18-round 9mm P226 magazines and gives you that extra round when you need it without changing your magazine profile.
This conversion kit contains three components: a new magazine spring, a high-impact polymer follower, and a polymer floorplate, all finished in black. Installation is simple since you're just replacing the internal guts of a magazine you already have. You keep the same mag body and get the upgraded capacity.
Mec-Gar magazines are known for quality, and this kit maintains that standard. The spring and follower are engineered to handle repeated loading cycles without losing their snap. The follower is specifically designed to work with the taller stack in an 18-round magazine, so capacity gains don't sacrifice feed reliability. Many people use these conversions on guns they trust with their lives, including those who carried them as duty weapons.
If you already own Mec-Gar 18-round P226 magazines, this conversion kit is the cost-effective way to get more capacity without buying entirely new magazines. Just note this kit is designed for the Mec-Gar 18-round spec, not factory Sig 15-round magazines.
No, this kit is specifically designed for Mec-Gar 18-round P226 9mm magazines. Factory Sig magazines have a different interior design and capacity, so using this kit with them won't deliver the intended plus-one result. If you own Mec-Gar mags, you're all set.
Installation is straightforward. You simply disassemble your existing Mec-Gar 18-round magazine, remove the old spring, follower, and floorplate, and swap them out for the new components. No special tools required. Most people can have it done in a few minutes.
Mec-Gar components are built to high standards and many people use these conversion kits in loaded carry guns. The spring and follower are engineered to feed reliably under repeated cycling and stress. That said, as with any modified magazine, it's smart to test it thoroughly at the range before depending on it for anything critical.
This Plus 1 kit is made for Mec-Gar Sig Sauer P226 18-round 9mm magazine bodies. You'll keep the same magazine shell you already own and simply swap out the internal components.
