The Blackhawk Stache IWB holster Size 78 is a purpose-built inside-the-waistband carry solution engineered for shooters who demand comfort and concealment without compromise. Built from impact-reinforced injection-molded polymer—a material choice that outperforms traditional Kydex in rigidity and comfort—this ambidextrous holster was designed by concealed carriers for the realities of everyday carry. Size 78 is engineered to fit the Sig P365XL, giving you a holster that matches your firearm's footprint and handling characteristics.
The Stache IWB prioritizes the concealed carry experience. A low-profile shirt guard keeps the holster comfortable against your body while staying out of the way during the draw. The 1.5" J-style belt clip is adjustable for both height and cant, so you can dial in the carry angle and position that works with your body, clothing, and shooting style. Friction-adjustable passive retention keeps your gun secure without fussy thumb breaks or additional manipulations. Ambidextrous design means it adapts instantly to right or left-hand carry—switch your carry side without swapping holsters.
Where the Stache IWB truly stands out is modularity. The holster is compatible with Discreet Carry Concepts Gear Clips Mod-4, allowing you to integrate it into a larger loadout. If your optics-equipped P365XL wears a red dot, this holster accepts handgun-mounted RDS optics without issue. That means no compromise on your gun's setup. Made in the USA, the Stache IWB delivers the kind of reliable, understated performance that doesn't rely on hype—just solid engineering.
