a first opening into the inner cavity adjacent to the first end of the unitary body;

a second opening into the inner cavity adjacent to the second end of the unitary body

an internal shoulder positioned within the inner cavity;

a first projection that extends from the internal shoulder;

a second projection that extends from the first end of the inner cavity; and

the unitary body selectively retains a firearm positioned within the inner cavity, wherein a force is applied to the firearm by the internal shoulder to selectively retain the firearm.

17. A firearm holster comprising:

a unitary body having an inner cavity configured to receive a firearm and a slide cap that partially encloses the inner cavity, the inner cavity having a first end and a second end opposite of the first end with the slide cap being adjacent the first end;

an internal shoulder positioned within the inner cavity; and

the unitary body selectively retains a firearm positioned within the inner cavity, wherein a force is applied to the firearm by the internal shoulder to push the firearm against the slide cap to selectively retain the firearm.

18. A firearm holster comprising:

a unitary body having an inner cavity configured to receive a firearm, the inner cavity having a first end and a second end opposite of the first end;

a first opening into the inner cavity adjacent to the first end of the unitary body;

a second opening into the inner cavity adjacent to the second end of the unitary body;

an internal shoulder positioned within the inner cavity;

one or more compression pads positioned adjacent to the inner cavity, wherein the one or more compression pads is configured to apply a force against a slide of a firearm positioned within the inner cavity; and

the unitary body selectively retains a firearm positioned within the inner cavity, wherein a force is applied to the firearm by the internal shoulder to selectively retain the firearm.

19. The firearm holster of claim 18 , further comprising a fulcrum cushion positioned adjacent to the inner cavity, wherein the fulcrum cushion is configured to apply a force against the slide of the firearm positioned within the inner cavity and provide a pivot point for rotation of the firearm within the inner cavity.
