COWCOW stainless steel hammer set

Match-grade hammer upgrade

The COWCOW stainless steel hammer set is a precision internal upgrade for Tokyo Marui Hi-Capa and 1911 gas blowback pistols. CNC machined from solid stainless steel, it replaces the softer factory hammer with a harder, more durable component built to survive heavy match use.

Built for consistency

The hammer is skeletonised and lightened to reduce reciprocating mass, which helps deliver a crisp and repeatable release. That consistency is exactly what IPSC and speed shooters look for when tuning a competition build.

Titanium Nitride finish

A Titanium Nitride (TiN) treated surface adds a hard, low-friction layer. This improves wear resistance and helps the internals cycle smoothly, keeping performance sharp over thousands of shots.

Fitting and compatibility

Designed as a drop-in Type B part for TM-spec Hi-Capa and 1911 frames, it pairs well with matched springs and sears. As with any internal work, we recommend fitting by an experienced technician. Explore more airsoft accessories and internal parts to complete your build.
