Sig Sauer P228, P229 18 RD 9mm anti-friction Mec-Gar MGP22818AFC



Mec-Gar Sig Sauer P228 or P229 semi-flush fitting 18 round 9mm anti-friction coating magazine MGP22818AFC. Mec-Gar now uses a newly designed follower and marks their adapter as being a +3 adapter. These magazines have an 18 round capacity, 5 more than the standard Sig factory P228 or P229 13 round magazine and 3 more than Mec-Gar's flush fitting 15 round magazines.

Does not fit the Sig Elite Classic Carry "talo edition" or Sig P229 Custom Carry Elite, the grip prevents the magazine from inserting all the way.

This is also the correct magazine for the Sig Sauer P229 Legacy.

  • Fits P228 and older P229 pistols with flat-sided narrow magazine
  • Not for use in P229 E2 pistols with wider tapered P229-1 magazine
  • Increased capacity to 18-rounds with "Plus-3" Adapter
  • Only 5/8" longer than flush-fit magazines
  • Redesigned tube to improve functionality, heat-treated for strength
  • Anti-Friction Coating allows for easy loading and superior anti-corrosion
  • Interlinked internal components
  • This is also the correct magazines for the Sig Sauer Classic Carry 9mm.
Mec-Gar Sig Sauer SCT style P228 or P229 18 round 9mm magazine with the anti-friction coating. This magazine is compatible with the Sig Sauer P229 9mm with the narrow tube magazines but not the newer P229-1 or P229 E2 style pistols that use the same width magazine as the P229 .40 S&W/.357 Sig. The Sig Sauer Elite Classic Carry 9mm uses the original style P228/P229 flat sided magazines. 
Most of the Sig Sauer P229 E2 9mm, Sig Sauer M11-A1 and Sig P229 made from late December 2010 now have a wider magwell which is the same a the Sig Sauer P229 .40/.357.  For those pistols you need to use a Sig Sauer P229-1 magazine. While these will lock in to place they will have some play in the magwell that may cause reliability issues. These magazines are for the P228 or P229 9mm that have the narrower magwell. 

Constructed from certified carbon steel and features a heat treated housing and high-impact polymer or certified carbon steel follower and floorplate. The magazine spring is made of high strength type "D" music wire-the strongest wire available. TIG welding provides additional strength and a seamless finish. Each magazine surface is specially treated to ensure high corrosion resistance.

These magazines meet the standards for the OEM mags and add additional rounds. They work without fail. I have over 2000 rounds through 3 mags I own with zero malfunctions, hang ups, misfeeds etc.... I will continue to buy Mec-Gar mags to run in my Sigs without hesitation.
