Description
This is the MEC-GAR MG20111800A, an 18-round magazine purpose-built for 2011, 2311, and Springfield Prodigy platforms in 9mm. You get one more round than the factory magazine while maintaining a flush fit with your grip. Made in Italy with heat-treated carbon steel and a protective anti-friction coating, these mags handle competition rounds and duty use with equal capability.
The design centers on reliability and consistency. A high-tensile music wire spring pairs with a high-impact polymer follower that's been optimized for smooth feeding without jams. The precision-fit body eliminates wobble in the magazine well, which matters when you're running the gun hard. A removable polymer baseplate makes disassembly and cleaning straightforward, and numbered witness holes let you track your round count without guessing.
MEC-GAR has been manufacturing magazines since 1965 and supplies OEM magazines to major firearms makers worldwide. These aftermarket magazines carry that same build quality and attention to detail. The anti-friction coating reduces wear on your hands during high-volume reloads and protects the steel from corrosion when stored loaded. Works with 2011 and 2311 pistols, Kimber 2K11, Springfield Prodigy, and other compatible 2011-pattern clones.

Frequently Asked Questions
Will this MEC-GAR magazine work in my Staccato pistol?
If your Staccato was made before August 2024, yes. STI/Staccato changed the frame dimensions on models after August 2024, which makes them incompatible with this and most aftermarket magazines. Check your manufacturing date to be sure.
Is this magazine flush fit with the grip?
Yes. The 18-round capacity gives you one additional round compared to factory magazines while still sitting flush with the grip. There's no basepad extension needed.
What makes the anti-friction coating useful?
The coating reduces friction when loading rounds and handling the magazine during reloads. It also protects the carbon steel from corrosion, which is important if you store the magazine loaded or in humid conditions.
Can I use this magazine for competition?
Yes. The precision-fit design and quality components make this magazine suitable for match-grade performance. The high-tensile spring and feed geometry ensure consistent operation under the demands of competitive shooting.
Is this a genuine MEC-GAR product?
Yes. MEC-GAR manufactures all of their magazines in Italy using the same technologies and materials they supply to major firearms manufacturers. Each magazine carries the same quality control standards as OEM magazines.
