Modular holster for a firearm

Abstract

A module holster includes a shell module and at least one adaptor module. The shell module defines a first interior space configured to receive the slide of multiple different firearms, including a predetermined firearm. The adaptor module defines a second interior space with internal geometry configured to receive a trigger guard of the predetermined firearm. The adaptor module is longitudinally slidably engageable with the shell module to form a holster body. The holster body defines a cavity in which the predetermined firearm is removably receivable and from which cavity the predetermined firearm resists extraction. A user may slidably disengage the adaptor module from the shell module and replace it with a different adaptor module defining a second interior space with internal geometry configured to receive the trigger guard of a different predetermined firearm.
