Three-Way Carry Explained

This holster is designed to support three proven OWB carry positions:

• Strong Side Carry – Traditional hip carry with a neutral draw angle
• FBI Mount (Forward Cant) – Angled forward for quicker draw and concealment under a jacket
• Crossdraw Carry – Ideal for seated carry, driving, or long hours on horseback or equipment

Carry position depends on belt placement and orientation. This holster supports all three without compromising fit.
