The forged steel slide features front and rear cocking serrations plus a factory optics cut set up for RMSc/507K footprints; the rear sight uses a Glock-pattern dovetail for easy aftermarket upgrades.
A 5-inch forged 4140 bull barrel with a QPQ bore finish and 1:10 RH twist delivers durability and consistent accuracy. The bore is bright and clean, reflecting minimal use.
The glass-filled polymer grip module offers 25 LPI checkering for confident control, while the skeletonized flat trigger breaks at a crisp 4.75 lb. A beavertail grip safety, thumb safety, and skeletonized commander-style hammer round out the Series-70 fire-control system.
With an unloaded weight of 32.5 oz and an accessory rail for lights or lasers, this 1911 Duty DS balances carry comfort with full-size shootability. Compatibility with STI/Staccato magazines expands aftermarket options for serious range or competition use.
