At least someone grasps that most of the so called 'semi auto' airguns aren't actually semi-automatic.
Now, I haven't owned a Steyr LP5 or LP50, but I have owned similar stick magazine CO2 and pcp 5 shot match pistols.
Once the magazine was inserted and the action cocked squeezing the trigger released the striker to fire the gun - the recocking of the striker and indexing of the magazine all occurred prior to the trigger being released for the next shot, this action being powered by a portion of the propellant gas.
Releasing the trigger only
reset the trigger mechanism to fire the next shot.
Now that is semi-auto in an airgun context.
