a latching receiver configured to receive and retain the firearm, the latching receiver comprising a latch pivotable about a second pivot point between a firearm engaging position and a firearm release position, the latch having a protrusion configured to engage and retain the firearm when the latching lever is in the first engaging position.

2. The retention device of claim 1 , wherein the latching receiver is biased toward the firearm engaging position by a spring.

3. The retention device of claim 1 , wherein the firearm trigger guard is configured to support the latching lever with a pin therethrough.

4. The retention device of claim 1 , wherein the protrusion is configured to engage a detent in the trigger guard of the firearm when in the firearm engaging position.

5. The retention device of claim 4 , wherein the latch is rotatable from the firearm engaging position to the firearm release position by movement of the latching lever from the first engaging position to the second release position.

6. The retention device of claim 4 , wherein the detent in the trigger guard is a groove therein.

7. The retention device of claim 6 , wherein the detent in the trigger guard includes a wear block where the detent contacts the trigger guard to prevent wear to the trigger guard.

8. The retention device of claim 1 , and further comprising a wear block configured to mount in the trigger guard of the firearm to engage the protrusion of the latch when the latch is in the firearm engaging position.

9. The retention device of claim 1 , wherein the latching receiver is mountable to a holster.

10. The retention device of claim 1 , wherein the latching lever comprises metal, alloy, composite plastic, carbon fiber, or a combination thereof.

11. The retention device of claim 1 , wherein the latching receiver comprises metal, alloy, composite plastic, carbon fiber, or a combination thereof.

12. The retention device of claim 1 , wherein the latching lever is movable from the first engaging position to the second release position by pressure on an end of the latching lever located at a pistol grip end of the latching lever.

13. The retention device of claim 1 , wherein the latching receiver is mounted in a holster, and wherein the latching receiver comprises an integral flexure device to provide stability and controlled placement to the firearm within the holster.

14. A method of securing a firearm to a receiver, comprising:

providing a latching lever mountable to a trigger guard of the firearm, the latching lever pivotable about a first pivot point between a first engaging position and a second release position;

providing a latching receiver configured to receive and retain the firearm, the latching receiver comprising a latch pivotable about a second pivot point between a firearm engaging position and a firearm release position, the latch having a protrusion configured to engage and retain the firearm when the latching lever is in the first engaging position; and

latching the firearm to the latching receiver.

15. The method of claim 14 , wherein latching the firearm to the latching receiver comprises engaging the latching receiver to the trigger guard by moving the latching receiver to the firearm engaging position and the latching lever to the first engaging position.

16. The method of claim 14 , and further comprising unlatching the firearm from the latching receiver by moving the latching lever from the first engaging position to the second release position.

17. A method of adding a retention device to a firearm, comprising:

mounting a latching lever to a trigger guard of the firearm; and

providing a latching receiver configured to receive and retain the firearm, the latching receiver comprising a latch pivotable about a latch pivot point between a firearm engaging position and a firearm release position, the latch having a protrusion configured to engage and retain the trigger guard when the latching lever is in the first engaging position.

18. The method of claim 17 , wherein mounting the latching lever to the trigger guard comprises drilling a hole in the trigger guard, routing a groove in a bottom of the trigger guard, and inserting the latching lever into the groove with a pin through the hole in the trigger guard and a hole in the latching lever.

19. The method of claim 18 , and further comprising mounting a wear block to the groove at a point where the protrusion engages the trigger guard to protect the trigger guard from wear.
