"Finally, the picture below is from the US range at Sea Girt in 1899. It shows a shooter in an unusual variant of the back position, known as the "Texas Grip" invented by Sergeant Tabler, of the 22d U.S. Infantry. The gun sling is under the left leg above the knee, that leg resting on the right, the right hand so placed that the trigger is pressed with the thumb, the left arm behind the head and the hand grasping the top of the butt."

The sling on a Trapdoor found a use there !
Cleaning from the muzzle is the only thing not fun about a Trapdoor.

Texas Grip brings new meaning to "trigger thumb."
