Abstract
A semi-automatic pistol is provided having a barrel, a frame and a slide. The slide is adapted for linear motion along the frame during a firing sequence and has a forward end and a block end. The forward end has an upper cam follower surface and a lower cam follower surface on the inside surface adjacent to the barrel. The barrel has a ramp cam surface adjacent to the chamber end of the barrel to effect locking and unlocking of the barrel relative to the slide during the firing sequence, a bottom cam surface and a top cam surface. The bottom cam surface and the top cam surface extend from the front end toward the chamber end of the barrel and each have undulating surfaces that moves against the lower cam follower surfaces of the slide to cause oscillation of the barrel while the slide moves during the firing sequence.
