Abstract
An ergonomic firearm grip includes a grip body having a front strap, a rear strap, a lower palm grip portion, and an upper firearm interface portion with parallel sides, a front interface end and a rear interface end, a rear strap extension connected to the rear strap adjacent the upper firearm interface portion where the rear strap extension has a rear curved surface portion that extends horizontally away from the rear strap at the junction of the rear strap extension and the rear strap and forming the rear interface end, and a front strap extension connected to the front strap where the front strap extension has a front curved surface portion that extends horizontally away from the front strap at the junction of the front strap extension and the front strap.
Claims20
An ergonomic firearm grip comprising:
- a grip body having a front strap, a rear strap, a lower palm grip portion, and an upper firearm interface portion with parallel sides, a front interface end and a rear interface end wherein the grip body extends at a downward vertical angle from a centerline of the upper firearm interface portion, the centerline of the upper firearm interface portion being parallel to a gun barrel and intersecting with the center of a trigger face on a firearm to which the firearm grip is attached;
- a rear strap extension connected to the rear strap adjacent the upper firearm interface portion wherein the rear strap extension has a rear curved surface portion that extends horizontally away from the rear strap at the junction of the rear strap extension and the rear strap to the rear interface end at least about 0.5 inches in an arc configuration and that extends from the rear strap a distance no greater than about 1.7 inches, the rear strap extension forming an arc with at least a 75 degree arc angle and an upper rear extension surface that extends rearwardly from the arc when the arc angle is less than or equal to 85 degrees, the upper rear extension surface being a rear extension surface having an angle of inclination to the horizontal from the rear curved surface portion no greater than 15 degrees;
- and
- a front strap extension connected to the front strap adjacent the upper firearm interface portion wherein the front strap extension has a front curved surface portion that extends horizontally away from the front strap at the junction of the front strap extension and the front strap at least about 0.5 inches in an arcing configuration, the front strap extension having an upper surface portion of the front curved surface portion that is parallel to the centerline of the upper firearm interface wherein the vertical distance between the upper surface portion of the rear strap extension and the upper surface portion of the front strap extension is in a range of about 0.8 inches to about 1.6 inches.

A method of making an ergonomic firearm grip comprising:
- forming a grip body having a front strap, a rear strap, a lower palm grip portion, and an upper firearm interface portion, a front interface end and a rear interface end wherein the grip body extends at a downward vertical angle from a centerline of the upper firearm interface portion, the centerline of the upper firearm interface being parallel to a gun barrel on a firearm to which the firearm grip is attached;
- forming a rear strap extension connected to the rear strap adjacent the upper firearm interface portion wherein the rear strap extension has a rear curved surface portion that extends horizontally away from the rear strap at the junction of the rear strap extension and the rear strap to the rear interface end of at least about 0.5 inches in an arc configuration and extends horizontally from the rear strap a distance no greater than about 1.7 inches, the rear strap extension forming an arc with at least a 75 degree arc angle and an upper rear surface extension of the rear curved surface portion that extends rearwardly from the arc when the arc angle is less than or equal to 85 degrees, the upper rear extension surface being a rear extension surface having an angle of inclination to the horizontal no greater than 15 degrees;
- and
- forming a front strap extension connected to the front strap adjacent the upper firearm interface portion wherein the front strap extension has a front curved surface portion that extends horizontally away from the front strap at the junction of the front strap extension and the front strap at least 0.5 inches, the front strap extension having an upper surface portion of the front curved surface portion that is parallel to the centerline of the upper firearm interface wherein the vertical distance between the upper surface portion of the rear strap extension and the centerline of the upper firearm interface portion is in a range of about 0.12 inches to about 0.62 inches.
