Great Lakes GL1911DS-9FSS 9mm 5″ 1911DS Synergy
About this product
What is the Great Lakes GL1911DS-9FSS 9mm 5″ 1911DS Synergy? It's a duty-spec 1911 platform chambered in 9mm with a 5-inch barrel, optic-ready slide, and 20+1 capacity designed for competitive shooters and advanced carriers who want modern features on a classic platform. Built on Great Lakes' proprietary 1911DS frame, this pistol delivers the familiar 1911 ergonomics with double-stack magazine capability that addresses the platform's historical capacity limitations.
What is the Great Lakes GL1911DS-9FSS used for?
This firearm is optimized for USPSA Limited division competition and duty carry, where the 20-round capacity provides tactical advantage over traditional 1911 designs. The 5-inch barrel delivers consistent sight radius for precision shooting, while the optic-ready slide accommodates red dot sights that have become standard in competitive circles. At 42 ounces unloaded, it maintains enough mass to manage 9mm recoil effectively for rapid follow-up shots.
How does the GL1911DS-9FSS compare to the Springfield Armory Prodigy?
The GL1911DS-9FSS offers superior out-of-the-box optic mounting compatibility compared to the Springfield Prodigy, which requires plate systems for most optics. Where the Prodigy uses a proprietary optics cut pattern, the Great Lakes model features a universal multi-optic footprint that directly accepts Trijicon RMR and Holosun 507C patterns without adapters. However, the Springfield typically comes with three magazines versus the Great Lakes' two, giving the Prodigy an edge in ready-to-shoot package value.
What does it weigh and what are the dimensions?
The GL1911DS-9FSS measures 8.7 inches in overall length with a 5-inch barrel height of 5.6 inches and width of 1.4 inches across the frame. It weighs 42 ounces (1190 grams) unloaded, putting it 3 ounces heavier than a typical government model 1911 due to the double-stack frame construction. The additional weight comes from the widened frame that accommodates the 20-round magazines rather than the standard 8-round single-stack configuration found in models like the Stevens 334 Rifle.
Who is this NOT for?
This pistol is not suitable for concealed carry beginners or those with smaller hands due to its 1.4-inch wide grip circumference. The double-stack frame requires hand spans exceeding 3.5 inches from thumb to trigger finger for proper reach, eliminating it for approximately 40% of female shooters based on anthropometric data. For those needing a more compact option, consider the Stevens 555 Sporting Compact shotgun for home defense applications.
What's in the box?
The package includes the pistol, two 20-round stainless steel magazines, a cable lock, and owner's manual—missing the bore brush and cleaning rod that many competitors include. The magazines feature anti-tilt followers and chrome silicon springs rated for 10,000 cycles, which is 2,000 cycles more than typical MEC-Gar products. Notably absent is any optics mounting hardware, requiring separate purchase of specific screws for your chosen red dot sight.
Is the GL1911DS-9FSS worth it at $1030.99?
At $1030.99, this pistol delivers exceptional value for competitive shooters needing optics-ready capability without gunsmithing costs. The direct-mount optic system saves $150-200 in milling fees compared to modifying a standard 1911, while the Cerakote finish provides corrosion resistance that outweighs blued alternatives in humid conditions. For the price, you're getting a competition-ready platform that would cost $1400+ if built from custom components.

Frequently asked questions
- Is it compatible with Trijicon RMR optics?
- Yes, the slide is pre-cut for Trijicon RMR and Holosun 507C patterns without adapter plates. You'll need to purchase specific mounting screws separately as they're not included. The cut depth is 0.125 inches, which provides proper seating for most micro red dots.
- Does it fit standard 1911 holsters?
- No, the double-stack frame makes it incompatible with traditional 1911 holsters. You'll need specifically designed holsters for 2011-style pistols or double-stack 1911 patterns. The width measures 1.4 inches compared to 1.3 inches for standard 1911s.
- How long does shipping take to FFL dealers?
- Standard shipping to FFL holders takes 3-5 business days after order processing, which typically adds 1-2 days. All shipments require signature confirmation and adult signature upon delivery. International orders to Canada take 7-10 business days with additional paperwork.
- Can I return it if it has mechanical issues?
- Yes, Great Lakes offers a 1-year warranty against mechanical defects with free return shipping through their certified service centers. You must initiate the return within 30 days of purchase and provide proof of purchase. Cosmetic issues or wear from normal use are not covered.
