The slide body defines an open region between the top wall and the side walls, the open region sized and configured to receive a barrel of the semiautomatic handgun extending along the bore axis and so that a muzzle end of the barrel is spaced axially from the distal end of the slide body. A distal end portion of the top wall defines one or more ports positioned between the distal end of the slide body and the muzzle end of the barrel to be received in the open region. ## Claims ### Claim 1 A slide for a semiautomatic handgun, the slide comprising: a top portion extending along a central axis; side portions connected to and extending downward from the top portion; a distal end connected to the top portion and side portions, the distal end defining a distal opening; wherein the slide defines an open region between the side portions and the top portion, the open region sized and configured to receive a barrel of the semiautomatic handgun so that a muzzle end of the barrel is spaced axially from the distal end of the slide; wherein the open region includes inclined top and bottom surfaces adjacent the muzzle end of the barrel to be received in the open region, the inclined top and bottom surfaces defining a barrel passageway in the distal end portion of the slide, wherein the barrel passageway is inclined at an angle from 5 to 30 degrees with respect to the central axis; and wherein a distal end portion of the slide defines one or more ports in the top portion, the one or more ports positioned between the distal end of the slide and the muzzle end of the barrel to be received in the open region, the one or more ports configured to vent a portion of gases exiting the barrel upon firing the handgun. ### Claim 2 (depends on 1) The slide of claim 1, wherein each of the one or more ports is defined in part by a proximally facing face of the top portion of the slide, wherein the proximally facing face extends perpendicularly to the central axis. ### Claim 3 (depends on 1) The slide of claim 1, wherein at least one of the one or more ports include a line of sight to the barrel, the line of sight within a cone with a cone angle of 75° or less. ### Claim 4 (depends on 3) The slide of claim 3, wherein the cone angle is 60° or less. ### Claim 5 (depends on 1) The slide of claim 1, further comprising a spring box on a bottom of the slide adjacent the distal end, at least a portion of the spring box is positioned distally of the muzzle end of the barrel to be received in the open region. ### Claim 6 (depends on 5) The slide of claim 5, wherein a majority portion of the spring box is positioned distally of the muzzle end of the barrel. ### Claim 7 (depends on 1) The slide of claim 1, wherein the angle is from 10-20 degrees. ### Claim 8 (depends on 1) The slide of claim 1, wherein the distal end of the slide is at least 15 mm beyond the muzzle end of the barrel when the barrel is installed in the open region. ### Claim 9 (depends on 1) The slide of claim 1, wherein the slide defines a barrel opening in the distal end portion, the barrel opening axially spaced from the distal opening and having a size that is smaller than the distal opening. ### Claim 10 (depends on 9) The slide of claim 9, wherein the distal opening has a non-circular shape. ### Claim 11 (depends on 10) The slide of claim 10, wherein a center of the distal opening is vertically offset with respect to a bore axis through a center of the barrel opening. ### Claim 12 A slide for a semiautomatic handgun, the slide comprising: a slide body extending along a bore axis and having a top wall, side walls extending downward from the top wall, and a distal end defining a distal opening intersected by the bore axis, the slide body further defining a recoil guide opening vertically below the distal opening; wherein the slide body defines an open region between the top wall and the side walls, the open region sized and configured to receive a barrel of the semiautomatic handgun extending along the bore axis and so that a muzzle end of the barrel is spaced axially from the distal end of the slide body; and wherein a distal end portion of the top wall defines one or more ports positioned between the distal end of the slide body and the muzzle end of the barrel to be received in the open region. ### Claim 13 (depends on 12) The slide of claim 12, further comprising a spring box extending rearwardly along a bottom of the slide body from the distal end, the spring box defining the recoil guide opening, wherein at least part of the spring box is positioned distally of the muzzle end of the barrel when the barrel is installed in the open region. ### Claim 14 (depends on 12) The slide of claim 12, wherein the slide body defines a barrel opening spaced axially from the distal opening, the barrel opening having a size that is smaller than the distal opening. ### Claim 15 (depends on 14) The slide of claim 14, wherein an inside of the slide body includes an inclined top surface and an inclined bottom surface defining the barrel opening therebetween, the inclined top and bottom surfaces inclined at an angle from 5 to 30 degrees with respect to the bore axis and defining a barrel passageway. ### Claim 16 (depends on 15) A recoil assembly comprising: the slide of claim 15; a barrel sized and configured to be received in the open region of the slide; a recoil spring guide having an end portion configured to be received in the recoil guide opening; a recoil spring configured to be installed on the recoil spring guide. ### Claim 17 (depends on 16) The recoil assembly of claim 16, wherein the barrel has a barrel length from 3.0 to 3.5 inches. ### Claim 18 (depends on 16) The recoil assembly of claim 16, wherein the barrel has a barrel length from 2.75 to 3.25 inches. ### Claim 19 (depends on 16) A semiautomatic handgun comprising the recoil assembly of claim 16. ### Claim 20 A slide for a semiautomatic handgun, the slide comprising: a top portion extending along a central axis; side portions connected to and extending downward from the top portion; and a distal end connected to the top portion and side portions, the distal end defining a distal opening; wherein the slide defines an open region between the side portions and the top portion, the open region sized and configured to receive a barrel of the semiautomatic handgun so that a muzzle end of the barrel is spaced axially from the distal end of the slide; wherein a distal end portion of the slide defines one or more ports in the top portion, the one or more ports positioned between the distal end of the slide and the muzzle end of the barrel to be received in the open region, the one or more ports configured to vent a portion of gases exiting the barrel upon firing the handgun; and wherein at least one of the one or more ports has a line of sight to the barrel, the line of sight within a cone with a cone angle of 75° or less. ### Claim 21 (depends on 20) The slide of claim 20, wherein the one or more ports are configured and arranged to reduce muzzle flip by venting combustion gases in an upward direction upon firing. ### Claim 22 (depends on 12) The slide of claim 12, wherein the one or more ports are configured and arranged to reduce muzzle flip by venting combustion gases in an upward direction upon firing.
