Description
If you own a Ruger SR1911 9mm, having quality factory magazines on hand is essential for range days, training sessions, or building a reliable carry rotation. This is the genuine factory-issue magazine that pairs with your pistol, manufactured to Ruger's exact specifications by Check Mate International right here in the USA.
Construction and Durability
The magazine features a laser-welded stainless steel body that delivers lasting durability and corrosion resistance in demanding conditions. The high-tensile steel spring and steel follower work together to ensure proper cartridge alignment and smooth operation. The stainless finish resists rust and degradation, so this magazine will continue performing whether you store it loaded for months or run it hard at the range. The numbered witness holes on the side let you confirm your round count at a glance without unloading.
SR1911 9mm Compatibility
This magazine holds nine rounds and works with full-size and Commander-style SR1911 9mm models. It delivers the standard load-out that your pistol was designed for. Keep in mind this is not compatible with the Officer-style SR1911 model, which uses a different magazine. The removable floor plate carries the Ruger logo, confirming this is a genuine factory unit.
Why an OEM Magazine Matters
Factory magazines are built to the exact tolerances and specifications of your firearm, guaranteeing drop-in fit and function without any guesswork. Since magazines see regular use and can wear over time, having spares or replacements means you'll always have a dependable option when you need it. This is true whether you're breaking in a new gun or replacing an older mag in your rotation.

Frequently Asked Questions
Will this SR1911 9mm magazine fit my Officer-style SR1911?
No, this magazine is designed for full-size and Commander-style SR1911 9mm models only. The Officer-style model uses a different, shorter magazine. If you have an Officer-style SR1911, you'll need the 7-round Officer magazine instead.

While some generic 1911 magazines may fit, factory Ruger magazines are built to the exact tolerances your gun was designed for, ensuring reliable feeding and function. Going with the genuine OEM magazine eliminates any compatibility questions and guarantees proper performance.
What are the numbered witness holes for?
The numbered witness holes on the side of the magazine let you quickly count your rounds at a glance without unloading the magazine. This is useful at the range or in training to verify you're loaded as expected, and the numbered markings make it even faster to count.
Is this magazine made by Ruger or someone else?
Ruger manufactures this magazine through Check Mate International, a contract manufacturer that produces magazines to Ruger's factory specifications. It's a genuine Ruger factory magazine, made in the USA, carrying the Ruger logo on the floor plate.
