The Mission First Tactical AIWB holster for the Sig Sauer P320 X-Carry and M18 is a versatile concealed-carry rig built for shooters who want one holster that adapts to multiple carry positions. Handcrafted to precise tolerances, this holster works inside the waistband at the appendix position, inside the waistband traditionally, or outside the waistband—all with the ability to switch between right and left-hand draw. It's the kind of no-compromise carry solution that works whether you're running appendix carry for quick access or switching to OWB for extended range sessions or duty use.

Comfort matters when you're carrying all day, and MFT engineered this holster with that reality in mind. The sculpted design accommodates an RMR or compatible red-dot sight mounted on your slide, and the abbreviated sweat guard keeps bulk down while still protecting your pistol and body from slide serrations and controls. Retention is adjustable, so you can dial in the exact security feel you prefer—and that famous audible click gives you positive confirmation on every holster and re-holster, dry or live.

The adjustable cant (0–15 degrees) lets you fine-tune your draw angle for comfort and presentation. Whether you carry deep concealment under a cover garment or prefer the speed and accessibility of appendix positioning, this holster adapts to your setup without requiring multiple purchases.
