Abstract

A semi-automatic firearm includes a frame and a movable slide mounted on the frame. The slide defines an ejection port and lateral walls that extend longitudinally from a rear face of the slide to adjacent a front face through which an opening is formed to permit egress of a round of ammunition, the rear face and the front face being generally perpendicular to the lateral walls. The firearm further includes a firing mechanism and an access port formed in the lateral walls of the slide.

Claims (26)

1. A semi-automatic firearm, comprising:

a frame;

a slide having an ejection port, said slide being slidably disposed for movement on said frame between one of a closed position and an open position and having a housing that extends longitudinally and substantially parallel to a direction of movement of said slide;

a firing mechanism including a sear assembly, said sear assembly including a sear housing and a sear guide wherein said sear assembly is slidably mounted within said sear housing and guided by said sear guide;

an access port formed in said housing; and

wherein said sear guide extends through a slot in said sear and a sear spring biases said sear into contact with the sear guide, said sear assembly being accessible through said access port to permit manipulation of said sear assembly therethrough.

2. The firearm of claim 1 , wherein in the dosed position, the access port is aligned with the sear.

3. The firearm of claim 2 , wherein inserting a probe into the access port and moving the sear with the probe permits the slide to be removed from the frame.

4. The firearm of claim 1 , wherein said the assembly further comprises a sear spring that biases the sear substantially toward the slide.

5. The firearm of claim 1 , wherein the sear assembly further comprises a pivot arm, wherein the sear is slidably attached to the pivot arm and the pivot arm is pivotally attached to the sear housing.

6. The firearm of claim 5 further comprising a magazine safety that impairs the movement of the firing mechanism so that the firing mechanism cannot be actuated.

7. The firearm of claim 6 wherein the magazine safety comprises a lever that engages a pin attached to the sear when the magazine safety is on, and thereby impairs lateral movement of the sear.

8. A semi-automatic firearm, comprising:

a frame;

a slide removably mounted on the frame, said slide defining an ejection port and lateral walls that extend longitudinally from a rear of the slide to adjacent a front face through which an opening is formed to permit egress of a round of ammunition;

a firing mechanism;

an access port formed in said lateral walls of said slide;

a magazine safety that impairs the movement of the firing mechanism so that the firing mechanism cannot be actuated, wherein the magazine safety comprises a lever that engages a pin attached to the sear when the magazine safety is on, and thereby impairs lateral movement of the sear; and

wherein the firing mechanism is accessible through the access port and can be manipulated to allow removal of the slide from the frame.

9. The firearm of claim 8 wherein the access port is aligned with the firing mechanism when the slide is in a chamber-closed position.

10. A semi-automatic firearm, comprising:

a frame;

a slide having an ejection port, said slide being slidably disposed for movement on said frame between one of a closed position and an open position and having a housing that extends longitudinally and substantially parallel to a direction of movement of said slide;

a firing mechanism including a sear assembly;

an access port formed in said housing, said access port being aligned with said sear when said slide is in said closed position; and

wherein inserting a probe into the access port and moving the sear with the probe permits the slide to be removed from the frame.
