Sig Sauer P229-1 E2 and M11-A1 10 RD 9mm Mec-Gar MGP22910B



Sig Sauer P229-1 E2 and M11-A1 10 RD 9mm Mec-Gar Magazine With The Blued Finish MGP22910B.

Most of the Sig Sauer P229 E2 9mm and Sig P229 made from late December 2010 now have a wider magwell which is the same as the Sig Sauer P229 .40/.357. For those pistols you need to use the Sig Sauer P229-1 magazine

The Sig Sauer P229 Classic Carry 9mm takes the narrower P228/P229 magazines. The P229-1 magazines are too wide for the magwell. 

If you have the earlier P228 or P229 9mm, Sig P229 Classic Carry or Sig P229 Legacy with the narrow magazine (came standard with a 13 round magazine) these magazines have too wide of a magazine tube, they won't fit. You need the original style P228/P229 magazines. Mec-Gar offers those in a flush fitting 15 round magazine or a 18 round magazine with a +3 adapter.

  • Fits newer P229, M11-A1 and P229 E2 pistols with wider tapered P229-1 magazine
  • Limited 10 round magazine
  • Will not fit in older P229 pistols with narrow flat-sided magazine
  • Redesigned tube to improve functionality, heat-treated for strength
  • Interlinked internal components

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.

I have bought ten of these for my Sig E2 and M11-A1 9mm pistols. They fit and work wonderfully! After shooting more than 500 rounds though each, there were no failures or misfires. The extra length gives a firmer and more accurate grip producing a better and more accurate shot. Great Cote is great to work with. They ship right away and I have never had a problem. I would recommend them to all.
