Check-Mate Industries has been manufacturing precision magazines for major firearm brands for decades — including serving as the OEM producer behind G3 Staccato 2011® magazines. When you buy Check-Mate 2011 magazines, you're getting the same manufacturing standards and materials used in factory-supplied magazines, available here as a standalone purchase at a competitive price point.
Check-Mate's 2011-pattern magazines are compatible with:
Note: Check-Mate 2011 magazines use Staccato-pattern geometry. Atlas-pattern magazines (MBX, Atlas Gunworks) use a different geometry and are not interchangeable. Verify your pistol's magazine well pattern before ordering.
Every Check-Mate 2011 magazine tube is manufactured from American-milled stainless steel, through-hardened for exceptional strength and durability, and polished inside and out to eliminate drag. The follower features Check-Mate's anti-friction, self-lubricating polymer for consistent feed and function. High-performance springs deliver outstanding reliability and long service life under the demands of competition shooting.
