Abstract

Disclosed is a firearm configuration for a handgun. The firearm configuration is designed to reduce the recoil forces encountered by a user upon firing the weapon. It further includes a recoil plate that absorbs forces generated by the slide during firing. Recoil forces are reduced by lowering the firearm's center of mass and by aligning a recoiling mass with the user's arm and trigger finger. The firearm configuration further includes a locking block which prevents rotational and lateral movement of the barrel upon firing.

Claims (24)

1. A firearm configuration for reducing recoil forces encountered by a user of a firearm, the firearm configuration being triggered by a user's trigger finger, the firearm configuration comprising:

an upper housing, the upper housing including a barrel and a firing assembly, the firing assembly arranged along an upper axis, the upper housing having a recoil mass;

a lower housing slidably interconnected to the upper housing, a trigger and trigger assembly positioned within the lower housing, the trigger assembly being interconnected to the firing assembly, the lower housing further including a guide rod and recoil spring engaging the recoil mass and arranged upon a lower axis, the recoil mass adapted for linear movement along the guide rod and lower axis continuously parallel to the upper axis and in alignment with a portion of the trigger that is configured to be engaged by the user's trigger finger to discharge the firearm;

wherein the lower axis (i) is disposed below and parallel to the upper axis, (ii) is disposed below and perpendicular to an axis of rotation of the trigger, (iii) passes through the portion of the trigger that is configured to be engaged by the user's trigger finger to discharge the firearm, and (iv) passes through a center of mass of the firearm; and

wherein after firing the firearm, the upper housing slides back with respect to the lower housing and the recoil mass slides rearwardly along the guide rod in a direction towards the trigger to thereby compress the recoil spring, and wherein the recoil of the firearm is reduced by positioning the recoil mass along the lower axis substantially in line with the user's trigger finger or arm.

2. The firearm configuration as described in claim 1 further comprising a magazine, the magazine configured to deliver ammunition upwardly into the upper housing between the barrel and the firing assembly.

3. The firearm configuration as described in claim 1 wherein the upper housing or substantial portion thereof is made of a material comprising aluminum, titanium, or a carbon fiber composite or a polymer.

4. The firearm configuration as described in claim 1 wherein a lower section of recoil mass is made of tungsten.

5. The firearm configuration as described in claim 1 wherein a lower section of recoil mass is made of bismuth.

6. The firearm configuration as described in claim 1 wherein a lower section of recoil mass is made of depleted uranium.

7. A firearm configuration for reducing recoil forces encountered by a user of a firearm, the firearm configuration comprising:

an upper housing, the upper housing including a barrel, a portion of the upper housing arranged along an upper axis, the upper housing having a recoil mass;

a lower housing slidably interconnected to the upper housing, a trigger and trigger assembly positioned within the lower housing, the trigger assembly being used to fire the firearm, the lower housing further including a guide rod and recoil spring interconnected to the recoil mass and arranged upon a lower axis;

wherein the lower axis (i) is disposed below and parallel to the upper axis, (ii) is disposed below and perpendicular to an axis of rotation of the trigger, (iii) passes through a portion of the trigger that is configured to be engaged by a trigger finger of the user to discharge the firearm, and (iv) passes through a center of mass of the firearm; and

wherein the recoil mass moves rearwardly upon firing and in a direction towards the trigger so as to reduce recoil forces upon firing.

8. The firearm configuration as described in claim 7 wherein the recoil mass is adapted for linear movement along the guide rod continuously parallel to the upper axis.

9. The firearm configuration as described in claim 7 further comprising a firing assembly arranged along the upper axis, the trigger assembly being interconnected to the firing assembly and being used to selectively actuate the firing assembly.

10. The firearm configuration as described in claim 7 wherein the recoil mass includes an opening and wherein the guide rod extends fully through the opening in the recoil mass.

11. The firearm configuration as described in claim 10 wherein there is a step formed within the opening of the recoil mass and wherein the recoil spring is positioned upon the step.

12. The firearm configuration as described in claim 7 wherein at least one surface of the recoil mass is sloped.

13. The firearm configuration as described in claim 7 wherein the upper housing or a substantial portion thereof is made of a material comprising aluminum, titanium, or a carbon fiber composite or a polymer.

14. The firearm configuration as described in claim 7 wherein a lower section of recoil mass is made of tungsten.

15. The firearm configuration as described in claim 7 wherein a lower section of recoil mass is made of bismuth.

16. The firearm configuration as described in claim 7 wherein a lower section of recoil mass is made of depleted uranium.
