Pistol slide-mounted suppressor
View Patent ↗A firearm suppressor configured for coupling to a firearm with its stock barrel bushing removed. The firearm suppressor includes a barrel bushing feature, a recess, and a release. The barrel bushing feature duplicates the barrel bushing of the firearm, which constrains the movement of the barrel of the firearm. The recess is positioned below the barrel bushing and is configured to receive and retain a cap of a recoil spring plug of the firearm. The firearm suppressor is coupled to the firearm when the cap of the recoil plug of the firearm is retained in the recess. The release is configured to press against the recoil spring plug of the firearm. Actuating the release pushes the recoil spring plug of the firearm away from the firearm suppressor, such that the firearm suppressor is removable from the firearm in the same manner as the original barrel bushing.
1. A firearm suppressor configured for coupling to a firearm comprising:
an elongate suppressor member having a passage there through;
a barrel bushing extending from an end of the elongate suppressor member with the barrel bushing configured for engaging with a barrel of a firearm, with the firearm including a recoil spring plug having a cap and including a slide with a locking key slot disposed therein;
a recess positioned below the barrel bushing and configured for receiving and retaining the cap of the recoil spring plug of the firearm, wherein the firearm suppressor is coupled to the firearm when the cap of the recoil spring plug of the firearm is retained in the recess and the barrel bushing is engaged with the barrel of the firearm; and
wherein the firearm suppressor further includes a release configured to press against the recoil spring plug of the firearm, wherein actuating the release pushes the recoil spring plug of the firearm away from the firearm suppressor, such that the firearm suppressor is removable from the firearm.
2. The firearm suppressor of claim 1 , wherein the barrel bushing comprises a locking key configured for engaging with the locking key slot of the slide of the firearm.
3. The firearm suppressor of claim 1 , wherein the release comprises a pair of levers retained with a screw.
4. The firearm suppressor of claim 3 further comprising a recoil spring plug plunger configured for contacting the cap of the recoil spring plug, wherein actuating the pair of levers of the release causes the release to contact and push the recoil spring plug plunger in a linear direction.
5. The firearm suppressor of claim 4 , wherein the recoil spring plug plunger comprises a slot for defining the linear travel of the recoil spring plug plunger, and wherein the recoil spring plug plunger is retained with a pin that is positioned in the slot.
6. The firearm suppressor of claim 1 , wherein the elongate suppressor member further comprises a suppressing mechanism configured for suppressing a sound intensity of a discharge of the firearm.
7. The firearm suppressor of claim 6 , wherein the suppressing mechanism comprises at least one of baffles, noise absorbing structures, and liquid impregnated materials.
8. The firearm suppressor of claim 7 further comprising an exterior casing configured for retaining and enclosing the suppressing mechanism.
9. The firearm suppressor of claim 1 , wherein the firearm is configured as an M1911 automatic pistol.
10. The firearm suppressor of claim 1 , wherein an end of the barrel of the firearm is unthreaded.
11. The firearm suppressor of claim 1 , wherein a cross-sectional outline of the elongate suppressor member is similar to a cross-sectional outline of the slide of the firearm.
12. The firearm suppressor of claim 1 , wherein the elongate suppressor member comprises an exterior casing and an internal frame, and wherein the external casing and internal frame may be either separate components or integrally formed.
13. A firearm suppressor configured for coupling to a firearm that includes a recoil spring plug having a cap and includes a slide with a locking key slot disposed therein, the firearm suppressor comprising:
a barrel bushing configured for sliding over a portion of a barrel of the firearm, wherein the barrel bushing comprises a locking key configured to engage with the locking key slot in the slide of the firearm;
a recess oriented below the barrel bushing and configured to receive and retain the cap of the recoil spring plug of the firearm, wherein the firearm suppressor is coupled to the firearm when the locking key of the barrel bushing is engaged in the locking key slot of the slide of the firearm and the cap of the recoil plug of the firearm is retained in the recess; and
a release configured to press against the recoil spring plug of the firearm, wherein actuating the release pushes the recoil spring plug of the firearm away from the firearm suppressor, such that the firearm suppressor is removable from the firearm.
14. The firearm suppressor of claim 13 further comprising an internal suppressing mechanism configured for suppressing a sound intensity of a discharge of the firearm, wherein the internal suppressing mechanism comprises at least one of baffles, noise absorbing structures, and liquid impregnated materials.
15. The firearm suppressor of claim 13 , wherein the firearm is configured as an M1911 automatic pistol.
16. The firearm suppressor of claim 13 , wherein an end of the barrel of the firearm is unthreaded.
17. The firearm suppressor of claim 13 , wherein a cross-sectional outline of the firearm suppressor is similar to a cross-sectional outline of the slide of the firearm.
18. The firearm suppressor of claim 13 further comprising an exterior casing and an internal frame, and wherein the external casing and internal frame may be either separate components or integrally formed.
19. A firearm suppressor comprising:
an elongate suppressor member comprising an external casing and an internal frame and having a passage there through;
a barrel bushing extending from an end of the elongate suppressor member, wherein the barrel bushing includes an outwardly projecting locking key;
a recess positioned below the barrel bushing;
a recoil spring plug plunger positioned at the recess;
a moveable release configured to contact and extend the recoil spring plug plunger into the recess; and
wherein the elongate suppressor member comprises at least one of baffles, noise absorbing structures, and liquid impregnated materials.
20. The firearm suppressor of claim 19 , wherein the release comprises a pair of levers or a slide and the recoil spring plunger includes a slot and is retained with a pin positioned within the slot, and wherein the slot defines a linear direction of travel of the recoil spring plunger, and wherein the barrel bushing is configured for sliding over a portion of a barrel of a firearm, wherein the locking key of the barrel bushing is configured to engage with a locking key slot in a slide of the firearm, wherein the recess is configured to receive and retain a cap of a recoil spring plug of the firearm, and wherein the release is configured to press against the recoil spring plug of the firearm.
