 As the slide and barrel separate, the spent case is ejected and the slide is then forced back to the barrel by a spring action, chambering a fresh cartridge in the process.The barrel and slide continue to the rear together in recoil for another before returning to the forward position.This feature improves the automatic fire accuracy, reduces felt recoil, and is responsible for slowing down the cyclic rate of fire, without using a sophisticated rate reducer mechanism such as the one employed in the APS pistol.
