Retention holster for a firearm having an offset mounted accessory

1. A holster, comprising:

a first side wall and a second side wall defining a cavity for receiving a handgun and an attached accessory, wherein the cavity defines a longitudinal axis of the holster, wherein the cavity includes a frame/slide portion and a trigger guard portion, and wherein the trigger guard portion is offset in a longitudinal and latitudinal direction from the longitudinal axis of the holster;

a one piece lever, wherein the lever includes a first side facing generally outward from the cavity and a second side facing generally toward the cavity,

wherein the lever is pivotally connected, via a pivot pin, atop the first side wall, approximately between a finger button end and an engagement end, such that a surface of the second side of the engagement end of the lever is positioned over an exterior surface of the first side wall,

a locking portion, wherein the locking portion extends from the surface of the second side of the lever,

wherein the lever is pivotable between an engaged position and a disengaged position and wherein the lever is biased to the engaged position, and

wherein, when the lever is in the engaged position, the locking portion protrudes through an opening in the first side wall, into the cavity, such that the locking portion extends into the cavity and inside an inner surface of the trigger guard of a handgun.

2. The holster of claim 1 , wherein the cavity includes a frame/slide portion and a trigger guard portion, and wherein a depth of the frame/slide portion is different from a depth of the trigger guard portion.

3. The holster of claim 1 , further comprises a front wall and a rear wall further defining the cavity.

4. The holster of claim 1 , wherein the walls of the holster are contoured to accommodate a specific type or model of handgun and accessory to be retained within the holster.

5. The holster of claim 1 , wherein the holster is substantially rigid.

6. The holster of claim 1 , wherein the holster is formed of a polymeric material.

7. The holster of claim 1 , further including at least one attachment point.

8. The holster of claim 1 , further comprising one or more slots, wherein the slots define a passive retention portion for providing frictional retention of the accessory by the passive retention portion.

9. The holster of claim 8 , wherein one or more retention screws may be tightened or loosened to adjust the degree of frictional retention between the passive retention portion and at least a portion of the accessory.

10. The holster of claim 1 , wherein the finger button end is positioned approximately above a frame of the handgun.

11. The holster of claim 10 , wherein the finger button end is positioned approximately above the handgun frame, between a trigger guard and a slide of the handgun, such that, as the handgun is withdrawn from the holster, the user's index finger is positioned to contact the handgun frame, between the trigger guard and the slide.

12. The holster of claim 1 , wherein the engagement end includes a ramp surface configured such that, as the handgun is inserted into the cavity of the holster, the trigger guard will contact the ramp surface and thereby displace the engagement end in a direction away from the trigger guard until a point at which the ramp surface is no longer in contact with the trigger guard, whereupon the engagement end will move in a direction toward the trigger guard and secure the handgun in the holster.

13. The holster of claim 1 , wherein the lever is biased, via a spring means, to the engaged position.

14. The holster of claim 1 , further including a ridge formed in the first side wall around at least a portion of the lever.

15. A holster for a handgun having an attached offset accessory, comprising:

a first side wall and a second side wall defining a cavity for receiving the handgun and the attached accessory, wherein the cavity defines a longitudinal axis of the holster, wherein the trigger guard portion is offset in a longitudinal and latitudinal direction from the longitudinal axis of the holster, and wherein the attached accessory is attached to and offset from a central axis of an accessory mounting rail of the handgun;

a one piece lever, wherein the lever includes a first side facing generally outward from the cavity and a second side facing generally toward the cavity,

wherein the lever is pivotally connected, via a pivot pin, to the first side wall approximately between a finger button end and an engagement end, such that a surface of the second side of the engagement end of the lever is positioned over an exterior surface of the first side wall, and wherein the pivot pin is positioned substantially parallel to a central vertical axis of the holster,

a locking portion, wherein the locking portion extends from the surface of the second side of the lever,

wherein the lever is pivotable between an engaged position and a disengaged position and wherein the lever is biased to the engaged position, and

wherein, when the lever is in the engaged position, the locking portion protrudes through an opening in the first side wall, into the cavity, such that the locking portion extends into the cavity and inside an inner surface of the trigger guard of a handgun.

16. The holster of claim 1 , wherein the finger button end and the engagement end are externally accessible.

17. The holster of claim 1 , wherein the at least the finger button end is uncovered.

18. The holster of claim 1 , wherein the engagement end is outside the cavity.

19. The holster of claim 1 , wherein the engagement end is atop an exterior surface of the first side wall.

20. The holster of claim 14 , wherein the pivot point is attached or coupled to the ridge.
