Bold Color, Serious Automatic Performance

The Heretic Colossus Auto OTF is built for users who want a larger, more commanding out the front automatic with unmistakable visual presence.

The Toxic Green aluminum handle is accented with a black traction inlay, adding grip and control without compromising the clean, tactical profile.
