Abstract

A grip strap is removably attachable to a grip of a firearm using a plunger mounted in the grip and biased by a mainspring which also biases a hammer strut of the firearm.

First claim

What is claimed is:

1. A firearm, said firearm comprising:
a frame defining a grip;
a hammer strut positioned within said grip;
a cup positioned within said grip;
a mainspring positioned within said grip and acting between said hammer strut and said cup;
a plunger mounted on said cup and extending through an opening in said grip;
a grip strap removably positionable on said grip, said grip strap comprising:
a strap portion overlying said frame, said strap portion having first and second ends oppositely disposed;
a spur projecting from said first end of said strap portion, said spur engaging a recess in said frame;
an aperture positioned in said second end of said strap portion, said aperture receiving said plunger, engagement of said spur with said frame and said plunger with said aperture retaining said grip strap to said grip.

2. The firearm according to claim 1 , wherein said aperture is defined by a lug projecting from said second end of said strap portion.

3. The firearm according to claim 2 , wherein said lug comprises a ramp surface surrounding said aperture, said ramp surface facing said plunger when said grip strap is retained to said grip.

4. The firearm according to claim 1 , further comprising a plate mounted on said grip, said plate defining said opening.

5. The firearm according to claim 4 , wherein said plate has a plate surface facing said mainspring, said plate surface surrounding said opening and defining a line of motion along which said plunger moves, such that movement of said plunger toward said mainspring compresses said mainspring.

6. The firearm according to claim 5 , wherein said mainspring comprises a coil spring surrounding an axis oriented parallel to said line of motion of said plunger.

7. The firearm according to claim 6 , wherein said axis is coaxially aligned with said line of motion.
