The disclosure relates to a firearm suppressor including a multi-material baffle configured to reduce at least audible discharge and muzzle flash. For example, a cone insert of the baffle may be formed of a first material, and a tubular member of the baffle may be formed of a second material different from the first material. The baffles may include a proximal circumferential flange having a plurality of through-wall ports through which fluid may be directed into a chamber defined by exterior surfaces of the baffles and the interior surface of an external can. The disclosure also relates to a firearm suppressor endcap having a plurality of through-wall ports radially disposed on a tubular body of the endcap, and a conical ramp configured to direct fluid across the conical ramp and through the plurality of through-wall ports of the endcap during operation of the suppressor.
