Description
The Check-Mate Full Size 1911 magazine handles .38 Super with the kind of precision engineering that comes from decades of manufacturing expertise. Built entirely in the USA from high-quality American milled stainless steel, each tube undergoes through-hardening for strength that holds up to extended range sessions and the demands of match competition.
What sets this magazine apart is the attention to detail in every component. The stainless steel tube gets polished inside and out to eliminate drag and ensure the follower moves smoothly with every reload. The flat follower features Check-Mate's anti-friction self-lubricating finish and is precisely dimpled for reliable feeding with .38 Super cartridges. Factory-drilled witness holes let you count rounds at a glance, and the high-tensile spring keeps that consistent feed cycle you count on.
At 9 rounds, the capacity aligns with standard full-size 1911 specs, giving you a clean flush fit that maintains your pistol's original profile. Whether you're prepping for a match, building out your range kit, or just want magazines that feed reliably every single time, this is the kind of gear that earns trust through performance rather than marketing noise.

Frequently Asked Questions
Will this magazine work with my Colt .38 Super 1911?
Yes, this magazine is designed for full-size 1911 pistols chambered in .38 Super and works with Colt and other standard full-size 1911 frames. The flush-fit profile means it won't stick out and maintains the original look of your gun.
What makes the Check-Mate magazine different from other brands?
Check-Mate has been manufacturing 1911 magazines as an OEM supplier for nearly 40 years and has fulfilled over 400 military contracts. This one uses American-milled stainless steel with through-hardening, polished interior and exterior surfaces, and a precision follower designed for smooth feeding. The anti-friction coating on the follower reduces wear over time.
Is this good for competition shooting or just range use?
This magazine performs equally well at the range or in competition. The precision fit, reliable feeding, and durable construction make it suitable for both environments. The witness holes also let you track your rounds during timed stages.
How many rounds does this hold?
This magazine holds 9 rounds of .38 Super ammunition, which is the standard capacity for full-size 1911 magazines in this caliber.
Does the magazine come with a base plate?
Yes, this magazine features a welded steel base that provides durability and strength. The welded base contributes to the overall rigidity of the magazine body.
Can I rebuild this magazine if the spring goes bad?
Check-Mate offers rebuild kits for their 1911 magazines, allowing you to replace springs and followers if needed. This extends the life of your magazines rather than replacing them entirely.
