a body configured to be partly received within a propellant chamber of a perf gun, and the body comprises an interface configured to engage a projectile;
a divider that defines part of the interface;
an ignition pass through that extends through the divider;
an ignition stack electrically connected to the ignition pass through;
a ground terminal electrically connected to the ignition pass through;
a deflector defined by the divider and having a cup-shaped configuration, and the deflector is configured to expand diametrically upon ignition of a propellant in the propellant chamber when the sabot is positioned within the propellant chamber;
a gas valve configured and arranged to be actuated by expansion of the deflector; and
a compensator positioned between the interface and the gas valve.
