9MM Dry Fire Action Stop

A neighbor of mine was practicing dry firing with his 9MM and was previously using a bobby pin to keep the action slightly open. However the bobby pin kept catching on his holster every time he would draw or stow his weapon during practice sessions. Without the bobby pin he couldn't practice pulling back on the trigger and dry firing so he either had a clumsy stow/removal or he couldn't dry fire.

He reached out to me to see if I could hook him up with something so I made this after taking so
