If you shoot a 9mm 1911, you’ll be interested in Check-Mate Magazines’ new Double-Stack Ultra-Hi Capacity magazine. It is designed to redefine standards in the industry and deliver an unparalleled combination of capacity, reliability, and compactness for double-stack 1911 enthusiasts.
Check-Mate responded to the demand for increased capacity by packing 19 rounds into the profile of a standard 17-round 9mm 1911 magazine. This magazine also maintains a flush-fit design to ensure seamless integration for your double-stack 1911 without compromising size or handling.
Backed by more than a decade of double-stack manufacturing expertise, Check-Mate says it has leveraged feedback from the largest brands and noted shooters in the firearms industry to develop what the company calls the most reliable and technologically advanced magazine on the market today.
Key features include the aforementioned 19-round capacity in a 17-round magazine’s profile, offering max firepower without added bulk or length, and an improved feeding angle to feed both hollow-point and FMJ ammunition more reliably, with a focus on consistent performance.
Check-Mate’s UHC 1911 magazine boasts patent-pending spring and follower technology designed to increase slide lock-back power by 50% to guarantee smooth operation and reliability all the way to the last round.

It is also built tough, with advanced materials, an all-metal aluminum basebad, and a steel retainer for durability and longevity. Each is proudly made in the USA.
