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;
