Owners of the Great Lakes Firearms 1911DS Synergy note that the double-stack 9mm configuration gives it a higher-capacity edge over single-stack 1911 builds. The Bull Shark frame draws attention as an unconventional polymer frame on a 1911-pattern pistol, and reactions are divided between those who prefer it for weight reduction and those who want a traditional all-metal build.

The 5-inch stainless barrel gets consistent praise for accuracy and finish quality. The trigger on the 1911DS gets mostly positive marks from owners familiar with 1911-type triggers, though those coming from striker-fired pistols find the reset and reset point different to learn.

For value, Great Lakes Firearms positions the Synergy below premium 2011-style double-stack builds, which appeals to buyers who want the platform without the cost of a higher-end brand. Some owners feel that the polymer frame undermines the premium feel relative to the price.
