EGW Government / Commander 1911 Titanium Mainspring Cap
Titanium Mainspring Cap That Solves Wear and Improves Long‑Term Reliability
The EGW titanium Mainspring Cap fixes the issues with Mainspring Caps that are worn out, mushroom, or deform over time. As a result, internal consistency declines and overall performance begins to suffer. Moreover, once deformation starts, shooters may experience inconsistent hammer energy, erratic trigger feel, premature mainspring fatigue, and reduced ignition reliability.
By contrast, upgrading to the EGW Government / Commander Titanium Mainspring Cap directly addresses these common issues. Because titanium is both stronger and lighter than steel, it preserves structural integrity while reducing internal drag. Consequently, spring compression remains consistent and ignition performance stays stable through extended round counts.
Advantages of a Titanium Mainspring Cap
Stronger, Lighter, and Built for High‑Round‑Count Use
To begin with, titanium offers an exceptional strength‑to‑weight ratio. Therefore, it withstands repeated spring compression without peening or deformation. At the same time, its reduced weight minimizes unnecessary mass inside the mainspring housing.
As a result, the EGW titanium mainspring cap delivers:
-
Consistent hammer energy
-
Smoother, more predictable trigger feel
-
Extended mainspring life
-
Reliable, repeatable ignition
Furthermore, because titanium resists corrosion entirely, performance remains unchanged even in humid, wet, or duty‑grade environments.
Precision EGW Manufacturing
Built to Exact 1911 Specifications
Equally important, EGW machines every titanium mainspring cap to precise Government and Commander 1911 specifications. Because ignition components demand exact tolerances, EGW maintains strict dimensional control throughout production.
Specifically, each cap is:
-
Precision machined from premium‑grade titanium
-
Held to extremely tight tolerances
-
Finished for smooth, low‑friction spring interaction
-
Inspected for dimensional accuracy and consistency
As a result, the cap installs easily, fits correctly, and functions flawlessly without fitting or modification.
