The blowback operation incorporates a feature somewhat reminiscent of Pedersen's hesitation locking that separates the slide and barrel as they move to the rear during recoil; there is no positive lock between the slide and barrel as in other conventional designs.
In the blowback mechanism, there is a feature that mirrors Pedersen's hesitation locking, where the slide and barrel detach as they retreat during recoil without a positive lock connecting them, unlike in typical designs.
