TMC Oversized Barrel Link Pin – Stainless Steel

TMC 1911 Oversized Barrel Link Pin – Stainless Steel

Precision Fit and Strength for Critical 1911 Lockup

To begin with, the TMC 1911 Oversized Barrel Link Pin delivers a tighter, more secure connection where it matters most. Unlike many factory pins that run slightly undersized, TMC machines this pin to the maximum allowable diameter (.154–.156″) specified on the 1911 part print. As a result, it restores proper fit in barrels with worn link‑pin holes—without exceeding spec.

Moreover, TMC heat treats and grinds each pin for long service life. Consequently, the pin resists wear, shear, and deformation under recoil, even in high‑round‑count pistols.

Why an Oversized Link Pin Matters

First and foremost, the barrel link pin connects the barrel link to the barrel lugs. Because this joint controls barrel tilt, timing, and lockup, even minor play can affect reliability and accuracy. Therefore, a properly sized pin plays a critical role in smooth cycling and consistent lockup.

By installing an oversized pin, shooters eliminate unwanted movement. As a result, the barrel locks up more consistently, returns to battery smoothly, and maintains predictable geometry shot after shot.

Precision Manufacturing and Materials

Built for Strength and Dimensional Accuracy

TMC machines each oversized link pin from hardened stainless steel, then heat treats it to precise specifications. In addition, final grinding ensures exact diameter and a smooth bearing surface.

Because stainless steel resists corrosion and galling, this pin performs reliably in duty, competition, and carry pistols. Furthermore, the natural stainless finish maintains a clean, professional appearance while standing up to harsh environments and frequent maintenance.

Performance Benefits

Improved Lockup and Long‑Term Reliability

With a tighter fit at the link interface, the barrel moves exactly as intended. Consequently, the slide and barrel unlock smoothly and lock consistently. At the same time, the pin reduces impact stress on the link and lugs, which helps extend the service life of critical components.

Additionally, the improved fit minimizes timing variation. Therefore, feeding reliability improves, accuracy becomes more repeatable, and the pistol feels smoother during recoil and return to battery.
