SDS 10100565 1911 DUTY B45RDG TH 45 5 FDE

The Tisas SDS 10100565 1911 Duty B45RDG TH in .45 ACP is a modern duty-grade pistol built for professionals who demand reliability, modularity, and suppressor compatibility. Chambered in the proven .45 ACP cartridge, this 1911 variant serves law enforcement, military, and serious civilian operators requiring a full-size platform that bridges proven 1911 ergonomics with contemporary tactical features. The forged steel frame provides the durability and longevity expected in demanding operational environments, while the Flat Dark Earth (FDE) Cerakote finish offers corrosion resistance and low-light visibility without glare.

The threaded barrel (TH designation) enables suppressor attachment, a critical advantage in tactical and training scenarios where hearing protection and signature reduction matter. The integrated RMSc/Holosun K optics cut allows rapid mounting of modern reflex sights, giving shooters the speed advantage of red dot aiming without requiring slide milling—the cut is machined to factory specification for rock-solid zero retention. At 4.23 lbs unloaded, the pistol balances a full-size grip and sight radius with manageable carry weight. The Raider platform foundation ensures field-proven reliability, while the durable Cerakote Custom finish resists wear in holster carry and harsh field conditions typical of duty use.

This pistol is ideal for uniformed officers, federal agents, and experienced shooters standardizing on suppressor-ready 1911 platforms. The threaded barrel requires compatible suppressors rated for .45 ACP and suitable thread pitch verification before installation. The RMSc/Holosun K footprint is widely supported across the industry, ensuring optic selection and future upgrades remain flexible. Standard 1911 ergonomics—thumb safety, grip safety, single-action trigger—remain unchanged, minimizing retraining for personnel transitioning from traditional 1911 duty guns. Magazine compatibility follows standard .45 ACP 1911 specifications, ensuring ready access to proven ammunition and spare magazines in operational settings.
