Check-Mate, a U.S.-based manufacturer specializing in high-reliability magazine systems and firearm components, proudly announces its collaboration with EAA Corp. on the launch of the next generation of Witness2311® pistols. Debuting at the NRA Annual Meeting 2026, the new XXX Series represents a significant advancement in compact, double-stack 1911 performance—driven in part by Check-Mate's cutting-edge magazine engineering.
Unveiled at the George R. Brown Convention Center in Houston, Texas, the latest Witness2311® models were developed in collaboration with global manufacturing partner Girsan and Check-Mate. At the core of this innovation is a newly engineered slim-profile magazine, purpose-built by Check-Mate to complement the compact grip module while maintaining a full 16-round capacity.
"Our collaboration with EAA on the Witness2311® platform is a testament to what can be achieved when performance engineering leads the conversation," said David Blenker, Chief Business Development Officer. "Designing a flush-fit, high-capacity magazine for a sub-compact 1911 variant required a relentless focus on geometry, materials, and reliability. The result is a magazine that enhances concealability without compromising capacity or function."
Check-Mate will be on-site alongside EAA Corp. at Booth 3031 during the NRA Annual Meeting, with a special launch event scheduled for April 17 from 11:00 a.m. to 12:00 p.m. Attendees, media, and industry partners are invited to experience the unveiling firsthand, with product demonstrations, presentations, and exclusive giveaways.
