Thunder Mountain Custom 1911 Improved S-7 Tool Steel Disconnector – Blued

Upgrade your 1911 with the Thunder Mountain Custom 1911 Improved Disconnector, a premium ignition component engineered for shooters who demand a cleaner, crisper, and more consistent trigger pull. Built from S-7 tool steel, this disconnector delivers outstanding durability, exceptional wear resistance, and long-term reliability inside any high-performance 1911 pistol.

Because Thunder Mountain Custom designed this part for serious competitors and enthusiasts, each disconnector comes pre-fit, polished, and ready for installation. You get smoother movement, a sharper break, and more dependable cycling without the need for additional gunsmithing.

Engineered for Maximum Reliability

Unlike mass-produced disconnectors that rely on softer alloys or inconsistent stamping, this model begins as fully machined S-7 tool steel—a shock-resistant, premium-grade metal known for surviving heavy impact and repeated stress. As a result, the part resists deformation, peening, and premature wear even in hard-running 1911 setups.

After machining, Thunder Mountain Custom hardens every disconnector and then polishes the slide notch and sear spring engagement surfaces. This creates clean, friction-free contact points that promote reliable cycling and a smoother trigger pull. Since the polishing preserves the part’s precise length and shape, you avoid the fitting problems found in many aftermarket components.

Drop-In Performance With a “Breaking-Glass” Trigger Feel

Because the surfaces arrive fully polished and dimensionally correct, the Auto Pro Improved Disconnector usually drops directly into your 1911. This helps shooters achieve the crisp, clean “breaking-glass” trigger feel that custom builders strive for during a professional trigger job.

Whether you are refreshing an older pistol, fine-tuning your competition setup, or building a match-grade 1911 from the ground up, this disconnector provides an instant upgrade in consistency and feel.
