For the serious shooter who demands precision, reliability, and tactical adaptability, the Springfield 1911 Master Class Silent Operator 45ACP Black Nitride with Threaded Barrel delivers a purpose-built platform straight from the factory.

The threaded barrel is the defining feature of this model, allowing direct attachment of a suppressor or compensator without the need for aftermarket machining. From home defense to range performance, this firearm is built for the operator who requires a silent, accurate, and durable sidearm.

Overview

The Springfield 1911 Master Class Silent Operator is a factory-tuned 1911 designed specifically for suppressed use. The 5-inch stainless steel barrel is threaded to standard 1/2-28 pitch, and the slide is fitted with a tall, suppressor-height front sight to clear a mounted can. The entire pistol is treated with a black nitride finish, which penetrates the metal surface for extreme hardness and a non-reflective matte appearance. The frame features an integral mainspring housing and an extended beavertail grip safety for a high-hand hold. Each pistol is shipped with two 7-round magazines and a bushing wrench. This is a full-size, steel-framed 1911 that retains the traditional grip angle and trigger geometry that has defined the platform for over a century.
