This gets me thinking (or trying to anyway). During recoil the sear bar is pushed back into place by the sear bar spring so as the receiver returns to battery the sear bar is going to catch the catch the firing pin anyway ... no? If the plunger were not spring loaded and unable to move backward when it made contact again with the trigger lever in essence you would have two pieces of steel (forward aspect of a "solid" sear bar and the trigger level) colliding unless you could pull AND release the trigger in the amount of time it takes the pistol to cycle. So maybe it purpose of the spring loaded plunger is to allow the shooter to hold the trigger back while the action functions and release the trigger in a more "reasonable" amount of time ?? Buys the shooter some time so to speak. O.K. ... how does that sound ???
