Trijicon Bright & Tough™ Tritium Iron Night Sight Set - Fits Colt 1911 Platforms (Post-1988 Govt/Delta) - 3-Dot Green/Green, .125" Wide-Tenon Stake-On Front - CA01-600138
Product Description
Upgrading a classic Colt Government, iconic 1911 platform, or hard-use tactical sidearm for low-light defensive tracking and rapid-indexing visibility reveals an immediate mechanical bottleneck: dull, non-illuminated factory iron sights. Standard white-dot or plain black GI blades require ample ambient lighting to track, leaving you completely blind during a midnight home-defense scenario or low-light staging block. The **Trijicon® Bright & Tough™ Tritium Night Sight Set (CA01-600138)** completely shatters these combat boundaries. Operating entirely without batteries or external electronic switches, this self-luminous iron sight overhaul injects constant, premium **green tritium** target reference lines onto your slide, maximizing low-light precision while maintaining your weapon’s timeless duty-grade geometry.
Precision-machined in the United States from a solid block of high-tensile **structural alloy steel billet**, the Bright & Tough series is engineered to absorb intense slide-velocity shocks and punishing daily field use. The exterior surface is treated with a uniform, non-reflective matte black finish that minimizes distracting glare under harsh sunlight on your workbench. Rather than using cheap plastic capsules that crack or leak, Trijicon packs its self-luminous tritium gas lamps inside a heavy-walled **aluminum cylinder shell**. This core module is cushioned inside an advanced **silicone rubber bedding ring**, isolating the delicate glass gas cells from hard recoil impulses and cross-axis directional g-forces when shooting heavy .45 ACP or 10mm Auto defensive payloads.
In fast-moving dynamic engagements, emergency defensive frames, or daytime marksmanship practice, the advanced physics of the **719307200029** sight array provide an immense tactical edge. The lamps feature a classic, high-contrast **3-Dot Green/Green arrangement** (two rear lamps, one front lamp) wrapped in prominent **white-painted outline rings** to enhance fast target acquisition in bright daylight. Each glass gas lamp is capped with a ultra-tough **sapphire jewel window cap**, which evenly distributes the green phosphor illumination while serving as an unyielding armor shield against harsh chemical bore solvents, carbon powder abrasion, and workbench punctures. Backed by Trijicon's legendary 12-year tritium radiance warranty, this factory-calibrated set replaces sluggish indexing with pure solid-state aiming authority.
*Armorer Bench Notes & Technical Field Installation Guidance: The Trijicon CA01-600138 sight configuration features an exact, mil-spec blueprint designed explicitly for **factory Colt 1911 Government, Combat Elite, and Delta Elite models manufactured after 1988**, as well as legacy Para-Ordnance P10 and P14 pistols equipped with a stake-on front sight. CRITICAL TENON INTERFACES & MOUNTING ADVISORY: This specific kit features a **.125-inch (Wide Tenon) stake-on front blade**. It will *not* fit older pre-1988 GI slides using the narrow .055-inch tenon slot, nor will it work on modern slides milled for Novak dovetails or Kimber-style cuts. **Armorer Workbench Installation Sequence:** Front sight installation requires professional armorer tool fixtures. The front sight tab must be driven straight down into the slide's vertical tenon window slot, and the internal protruding steel leg must be swaged or peened completely flat using a dedicated **1911 Front Sight Staking Tool Kit** over a secure bench block. **Rear Dovetail Rules:** The rear sight utilizes a standard factory GI style dovetail slot. Push the factory sight out from left to right on your bench using a heavy-duty sight pusher or a non-marring brass drift punch. Slide the Trijicon rear sight in from right to left, verify perfect visual centerline tracking, and lock it tight. Never strike the tritium sight body directly with a hardened steel hammer, as violent localized steel shocks can burst the internal glass lamps.*
