On my Beretta 92A1, there is a plunger and spring with a pin on the right side of decocker on the slide. The tip of the pin protrudes down into a slot in the slide that interfaces with the rear end of trigger bar. I know the decocker mechanism is actually a lobe on the shaft of the decocker in the center of slide underneath. With the slide off the frame you can press down on the decocker arm (adjacent to the ejector) and the hammer will fall (might want to prevent hammer falling with slide off). What function is performed by the interface of the rear of trigger bar with that pin? Seems that when the pistol is “off safe” the pin will not push down and hit the trigger bar. When the pistol is “on safe” the pin protrudes into the slot and would touch the trigger bar. Is this the mechanism that disconnects the trigger from the hammer when “on safe”? Thanks.
