Frequently Asked Questions
Will this Check-Mate magazine work in both a Sig P938 and Springfield 911?
Yes. Check-Mate manufactures OEM-spec magazines for both the Sig Sauer P938 and Springfield Armory 911 9mm platforms. This magazine is designed to function reliably in both pistols since they share the same magazine format.
Is the 6-round or 7-round magazine better for the P938?
The 6-round magazine provides a flush-fit option that keeps your pistol compact and concealable, matching the P938's pocket-pistol purpose. The 7-round extends beyond the grip and offers slightly better hand control. Choose 6-round if concealability is your priority, or 7-round if you want extra grip real estate and one more round.
Is this a quality magazine for everyday carry?
Check-Mate's magazines are manufactured entirely in the U.S.A. with a focus on performance, reliability, and fit. The stainless steel construction resists corrosion, making it suitable for daily carry environments. It's a straightforward, no-nonsense option for those who need dependable function.
Does the magazine come with a baseplate I can customize?
This magazine comes as a complete unit with the baseplate attached. If you want to swap the baseplate later, Check-Mate offers compatible rebuild kits and replacement baseplates that fit the P938 and 911 magazine platform.
What's the difference between the Check-Mate magazine and the factory Sig magazine?
Check-Mate makes OEM-spec magazines for Sig Sauer, meaning the design and engineering meet factory standards. The main practical differences are price and the polished stainless finish. Performance and function match what Sig P938 owners expect.
Can I use this magazine with other pistols besides the P938 and 911?
This magazine is engineered for the Sig P938 and Springfield 911 form factor. While some compact 9mm pistols may share similar footprints, we can only guarantee reliable function with P938 and 911 platforms.
