SDS Imports 80001507 Checkmate 1911 Double Stack 17rd 9mm Chrome

The SDS Imports Checkmate 1911 double-stack 17-round 9mm magazine is a high-capacity spare or replacement mag built for modern 2011-platform pistols. If you run a Tisas or MAC double-stack 1911 in 9mm and want to extend your on-hand ammunition capacity without swapping guns, this 17-round magazine gives you nearly double the firepower of a standard single-stack 1911 mag — ideal for the range, competition, or defensive training where reloads matter.

Checkmate brings decades of magazine manufacturing expertise to this design. The chrome finish resists corrosion and shows wear slowly, and the plastic base plate keeps weight minimal while remaining durable enough for thousands of cycles. The 17-round capacity is made possible by the double-stack geometry of compatible 2011 frames, so compatibility matters: confirm your pistol is a true double-stack 1911 (Tisas Military Armament Corp models are the primary match) before ordering.

Whether you're building a backup magazine set, stocking spares for a duty or competition pistol, or simply want the capacity advantage of a modern 2011 platform, this mag delivers straightforward reliability at a practical price point. It's the kind of part you buy several of and forget about until you need one.

Frequently Asked Questions

Will this magazine fit my 1911?

The SDS Imports Checkmate 17-round mag is designed for Tisas and MAC double-stack 1911 (2011-platform) pistols in 9mm. Standard single-stack 1911 frames will not accept this magazine. Double-check your pistol's frame design before purchase—if you're unsure whether it's a true double-stack, contact the pistol's manufacturer or your local gunsmith.

What's the advantage of 17 rounds over a standard 1911 magazine?

Standard single-stack 1911 magazines typically hold 7–8 rounds. The double-stack 1911 frame accommodates a wider magazine body, allowing this Checkmate mag to hold 17 rounds of 9mm ammunition. That extra capacity is valuable for range training, competition shooting, or defensive practice where fewer reloads mean more focus on marksmanship.

Is the chrome finish durable?

Yes. Chrome plating resists corrosion and fingerprints, and it develops character over time rather than showing rust. The finish is standard on quality magazines and will hold up through regular use and storage.
