The Osiris is our overt OWB holster well suited for IDPA, USPSA, and general range use when paired with an appropriate belt mount (sold separately).  It’s designed to work within IDPA rules, USPSA Production, and many other competitions.  Please read the rules to ensure you select the proper hardware.


We suggest most Safariland mounts, some G-Code, Invictus Practical, Blade-Tech large Tek-Loks, the Henry Holsters Turbo Drop, and the BOSS Hanger.    We do include three screws, posts, and spacers that will work with most attachments.


This holster fits all variants of the Sig Sauer P320 series except the sub-compact and rounded trigger guard models.
