Frequently Asked Questions
Will this holster fit my Sig P365XL with a red dot optic installed?
Yes — the BLACKHAWK Stache IWB Base Kit is specifically designed to accommodate the Sig Sauer P365XL with many popular red dot sights mounted. The optic-clearance cut in the holster body allows a proper fit and full trigger guard coverage even with a sight installed. If you are unsure about a specific optic footprint, contact BLACKHAWK customer support to confirm compatibility before purchasing.
Can I adjust the cant and ride height on the Stache holster?
Absolutely. One of the Stache's standout features is its high degree of adjustability. You can configure the cant angle (straight or forward-leaning) and ride height (low or high) to match your preferred carry position. The included 1.5" J-style belt clip provides a solid, adjustable foundation, and the holster is also compatible with Discreet Carry Concepts Gear Clips™ (sold separately) for even more mounting configurations.
Is the Stache Base Kit a complete holster, or do I need to buy additional components?
The Stache Base Kit includes the injection-molded holster body and a 1.5" J-style belt clip — everything you need to begin carrying right out of the box. It is a complete, functional IWB holster as supplied. However, the modular Stache system also supports optional upgrades such as the Premium Kit (which adds a padded backer and additional clips) and Discreet Carry Concepts Gear Clips™, all sold separately if you choose to expand your setup later.
