About this product
What is the Great Lakes GL1911DS Synergy 1911 DS? The GL1911DS is a double-stack 9mm 1911 pattern pistol with a 5-inch barrel and RMSc optic cut, offering modern capacity in a classic platform. It features a bronze Cerakote stainless steel frame paired with a black Cerakote slide and ships with fiber optic sights and two magazines. For shooters considering a traditional over/under pattern, our Stevens 555 Sporting 12 Gauge provides a different kind of platform mastery.
What is the GL1911DS Synergy used for?
This pistol serves practical range training and competition use where high capacity and optic-ready performance matter. The 5-inch barrel provides a 34.3-ounce unloaded weight that balances well for controlled rapid fire, while the RMSc footprint accepts popular micro red dots. It's built for shooters who need reliable function through extended sessions.
How does the GL1911DS Synergy compare to a Springfield Armory Prodigy?
The GL1911DS offers a more cost-effective entry into double-stack 1911s while the Prodigy typically delivers superior out-of-box trigger feel. Springfield's offering averages a 4.2-pound trigger pull versus the GL1911DS's 5.5-pound factory setting, but you save approximately $300 upfront. The Prodigy has better resale value, but the GL1911DS delivers functional performance at a lower price point.
What does it weigh and what are the dimensions?
Unloaded weight measures 34.3 ounces (972 grams) with an overall length of 8.7 inches. Barrel length is precisely 5.0 inches with a 1:16 twist rate, and the grip width measures 1.45 inches across the double-stack frame. These dimensions make it comparable to standard government model 1911s despite the increased magazine capacity.
Who is this NOT for?
This pistol isn't ideal for concealed carry due to its 8.7-inch length and 34.3-ounce weight. Shooters preferring single-stack slimness or traditional .45 ACP chambering should consider alternatives like standard 1911 patterns. Those needing suppressor-ready threading should look at models with pre-threaded barrels.
What's in the box?
You receive the pistol, two 17-round magazines, a cable lock, and owner's manual. The magazines feature anti-tilt followers and steel base plates for reliable feeding. No optic plate is included despite the RMSc cut, requiring separate purchase for red dot mounting.
Is the GL1911DS Synergy worth it at $1004.99?
At this price, it delivers solid value for a double-stack 1911 with modern features. Compared to custom builds starting at $1,800+, it provides 85% of the performance for 55% of the cost. For hunters needing a different toolset, our Stevens 334 in .308 Win offers precision at a lower price point.

Frequently asked questions
- Is it compatible with standard 1911 holsters?
- No, the double-stack frame requires specific holsters designed for wide-body 1911 patterns. The grip measures 1.45 inches wide versus 1.28 inches on traditional single-stack models. Check with manufacturers like Safariland or Blackhawk for compatible models.
- Does it fit Holosun 407K optics?
- Yes, the RMSc footprint directly accepts Holosun 407K and 507K models without adapter plates. Mounting requires proper torque specification of 15 inch-pounds on the optic screws. The fiber optic front sight provides lower-third co-witness through the optic window.
- How long does shipping take?
- FFL shipments typically process within 2 business days with 3-7 day transit time. All firearms require shipment to your local FFL holder for background check completion. Contact your receiving FFL before ordering to confirm their transfer fees and availability.
- Can I return it if there are mechanical issues?
- Ironclad Armory offers a 30-day warranty inspection period for manufacturer defects. Cosmetic issues or buyer's remorse returns aren't accepted due to federal firearm regulations. Document any malfunctions with video evidence and contact customer service within 14 days of receipt.
- Does this work with standard 1911 triggers?
- No, the double-stack frame requires specific trigger components different from single-stack 1911 patterns. The factory adjustable trigger has a 5.5-pound pull weight out of the box. Aftermarket support exists but requires verification of DS-compatible parts from manufacturers like EGW or Wilson Combat.
