Frequently Asked Questions
Will this holster fit a Sig P365 with a red dot optic installed?
Yes. The BLACKHAWK Stache IWB Base Kit is specifically designed to accommodate the Sig P365 with many of today's most popular red dot sights mounted to the slide. If you're running a larger optic footprint, we recommend verifying your specific optic dimensions against BLACKHAWK's fitment guide before purchasing.
Can I adjust the cant and ride height on the Stache holster?
Absolutely. The Stache's modular design allows you to configure ride height (low or high) and carry angle (straight or canted) to match your preferred draw stroke and body type. The included 1.5" J-style belt clip provides a solid baseline, and the system is also compatible with Discreet Carry Concepts (DCC) Gear Clips for even more mounting flexibility.
What is the difference between the Stache Base Kit and the Stache Premium Kit?
The Base Kit includes the injection-molded holster body and a single 1.5" J-style belt clip — everything you need to get started with IWB carry right away. The Premium Kit typically adds additional accessories such as a second clip style or a holster pouch for enhanced modularity. If you plan to expand your carry setup over time, BLACKHAWK's Stache accessories are sold separately and are fully compatible with the Base Kit platform.
