TMC 1911 Barrel – .45ACP – Government – Non-Ramp – 4140 Carbon Steel – QPQ Finish

Upgrade your 1911 with precision and reliability using the TMC Semi Drop-In Government 1911 Barrel in .45ACP. Whether you are replacing a worn barrel or building a new 1911, this barrel delivers consistent performance, durability, and accurate fit. Because it is made from 100% American 4140 carbon steel, you can trust its strength and longevity.

Precision Engineering for Accuracy

TMC hammer-forges this barrel over a precision mandrel held within .0001″, while maintaining bore tolerances within .0002″. As a result, each shot travels with consistency, giving you improved accuracy and confidence.

In addition, the polished bore features a surface finish of 16 microns or better, which enhances bullet travel and simplifies cleaning. Because the barrel is heat treated to 44 RC, it resists wear while maintaining strength under heavy use.

Reliable Feeding

This barrel incorporates a National Match feed ramp, which improves feeding reliability with a variety of bullet profiles. Whether you use hollow points, coated bullets, or traditional ball ammunition, you can expect smooth and consistent cycling.

The non-ramped, standard GI design makes this barrel ideal for traditional Government-style 1911 builds. As a result, it works perfectly with classic frames and slides while maintaining dependable performance.

QPQ Finish for Durability

TMC applies a QPQ finish to the barrel, increasing surface hardness and corrosion resistance. Because this finish reduces friction and prevents rust, the barrel maintains a clean appearance and long-lasting performance even under heavy use.

Notes on Fitting

Because 1911 slides and frames vary widely, minor fitting may be required. This is normal for semi drop-in barrels and ensures a precise, secure fit.
