The muzzle mount, baffle cups, and end cap thread together at threaded interfaces. Each baffle cup has an externally threaded proximal segment threadably received in the proximally adjacent component. The distal baffle cup has an externally threaded distal segment received in the end cap. The components are shaped and arranged to form sealed interfaces upstream of the threaded interfaces along the flow path of gas through the suppressor. The baffle cups include baffle walls defining chambers sized and arranged to limit first round pop. The baffle walls define vent passages extending along axes oriented at skew angles with respect to the axes of the baffle cups. A distal baffle cup includes an annular recess for reducing the weight of the suppressor adjacent the distal end. ## Claims ### Claim at position 1 1-24. (canceled) ### Claim 25 A baffle cup for use in a firearm suppressor, the baffle cup comprising: a generally conical baffle wall having a cone axis, a proximal end portion and a distal end portion spaced apart from one another along the cone axis, and a diameter, the diameter of the conical baffle wall increasing as the conical baffle wall extends from adjacent the proximal end portion toward the distal end portion, the conical baffle wall defining a bore extending along the cone axis; a flange portion extending radially outward from the proximal end portion of the conical baffle wall and having a proximal end oriented transverse to the cone axis and an opposite distal end; a vent passage extending along a venting axis oriented at a skew angle with respect to the cone axis, the vent passage including a first segment formed in the proximal end, and a second segment formed in at least one of the flange portion and the conical baffle wall, the first and second segments of the vent passage each extending along the venting axis. ### Claim 26 (depends on 25) A baffle cup as set forth in claim 25 wherein the first segment of the vent passage comprises a groove formed in the proximal end of the flange portion. ### Claim 27 (depends on 26) A baffle cup as set forth in claim 26 wherein the second segment of the vent passage comprises a vent hole having an opening through said at least one of the flange portion and the conical baffle wall, the opening being entirely enclosed by said at least one of the flange portion and the conical baffle wall. ### Claim 28 (depends on 27) A baffle cup as set forth in claim 27 wherein the vent hole opening has a cross-sectional shape in a plane orthogonal to the venting axis, the baffle cup having an imaginary volume defined by moving said cross-sectional shape along the venting axis over an entire length of the vent passage, the imaginary volume being free of material of the conical baffle wall and the flange portion. ### Claim 29 (depends on 25) A baffle cup as set forth in claim 25 wherein the vent passage opens on sides of the baffle cup that are opposite to each other with respect to the cone axis. ### Claim 30 (depends on 29) A baffle cup as set forth in claim 29 wherein the first segment opens to one of the sides of the baffle cup and the second segment opens to the opposite side of the baffle cup. ### Claim 31 (depends on 29) A baffle cup as set forth in claim 29 wherein the flange portion includes a proximal end segment adjacent the first end having a substantially cylindrical outer surface. ### Claim 32 (depends on 25) A baffle cup as set forth in claim 25 wherein the skew angle is in a range of from about 55° to about 85°. ### Claim 33 (depends on 25) A suppressor comprising the baffle cup of claim 25. ### Claim 34 (depends on 25) A kit for forming a suppressor comprising the baffle cup of claim 25. ### Claim 35 A method of forming a baffle cup for use in a firearm suppressor, the method comprising: forming a wall extending along a baffle cup axis and extending circumferentially around the baffle cup axis to define a cup passage along the baffle cup axis; and forming a vent passage in the wall having a first segment and a second segment disposed on an opposite side of the baffle cup passage from the first segment by inserting a material removing tool through the wall along a venting axis oriented at a skew angle with respect to the baffle cup axis. ### Claim 36 (depends on 35) A method as set forth in claim 35 wherein the step of forming the wall includes forming a proximal end of the wall and the step of forming the vent passage includes forming an open groove in the proximal end of the wall. ### Claim 37 (depends on 36) A method as set forth in claim 36 wherein the step of forming the groove forms the first segment of the vent passage. ### Claim 38 (depends on 35) A method as set forth in claim 35 wherein the step of forming the vent passage includes forming hole through the wall such that the wall extends circumferentially around the hole about the venting axis. ### Claim 39 (depends on 38) A method as set forth in claim 38 wherein the step of forming the hole forms the second segment of the vent passage. ### Claim 40 (depends on 35) A method as set forth in claim 35 wherein the step of forming the wall comprises forming a conical portion having a narrow proximal end and an enlarged distal end and forming a flange portion extending radially outward from adjacent the narrow proximal end of the conical portion, and wherein the step of forming the vent passage comprises forming at least a portion of each of the first and second segment of the vent passage in the flange portion of the wall. ### Claim 41 A suppressor for suppressing a blast of a firearm, the suppressor comprising: a baffle cup assembly including at least first and second baffle cups threaded together to form a threaded interface of the baffle cups, the baffle cup assembly having a projectile passage along which a projectile can pass along a projectile axis, the first and second baffle cups including respective shoulders in engagement with each other to form a sealed interface between the first and second baffle cups, the sealed interface being located upstream from the threaded interface with respect to the projectile passage, and a housing that houses the baffle cup assembly, wherein the housing and baffle cup assembly are arranged to define an interstitial space between the baffle cup assembly and the housing, the interstitial space extending circumferentially around the baffle cup assembly, the interstitial space being sealed from gas flow from the projectile passage at least in part by said sealed interface. ### Claim 42 (depends on 41) A suppressor as set forth in claim 41, wherein the housing includes a tube housing the first and second baffle cups, the tube being free of direct contact with the first and second baffle cups, the interstitial space defining a circumferential air gap between the tube and the first and second baffle cups to limit heat transfer from the first and second baffle cups to the tube.
