TMC 1911 Barrel – 45ACP – Gov – Non Ramp – Semi Drop-In Kit

TMC 1911 Barrel – .45ACP – Government – Non‑Ramp – QPQ Finish

Upgrade your 1911 with confidence using the TMC Semi Drop‑In Government 1911 Barrel in .45ACP. Whether you are replacing a worn barrel or starting a fresh build, this barrel delivers accuracy, durability, and consistent performance. Because TMC machines every barrel to tight tolerances, you get a precise fit and reliable function from the start.

Precision Manufacturing for Superior Accuracy

TMC hammer forges this barrel over a precision mandrel held within .0001″, while maintaining bore tolerances within .0002″. As a result, the barrel delivers excellent consistency shot after shot. In addition, the polished bore features a surface finish of 16 microns or better, which improves bullet travel and simplifies cleaning.

Furthermore, TMC manufactures this barrel from 4140 carbon steel and heat treats it to 44 Rockwell C. Because of this process, the barrel resists wear while maintaining strength under heavy use.

Reliable Feeding and Smooth Function

This barrel incorporates a National Match feed ramp, which improves feeding reliability across a wide range of bullet profiles. As a result, hollow points, coated bullets, and traditional ball ammunition feed smoothly and consistently.

In addition, the non‑ramped, standard GI configuration makes this barrel ideal for classic Government‑style 1911 builds that use a traditional frame setup.

QPQ Finish for Durability and Protection

TMC finishes this barrel with a QPQ treatment, which increases surface hardness and corrosion resistance. Because of this finish, the barrel resists wear, reduces friction, and maintains a clean, professional appearance even after extended use.

Kit Includes Essential Components

This barrel kit includes key parts to simplify installation and setup:

• Pre‑fitted barrel bushing
