The Definition of Checkering
A regular pattern of fine grooves cut into
the surface of a stock to aid in gripping a gun. Originally done for utility only,
checkering has become an art form in itself; craftsmen adorning the borders with ribbons,
fleur-de-lys, floral carving, etc. The amount of coverage, the precise regularity, and the
number of lines per inch indicate the quality of the work. Too-fine checkering, however,
defeats the purpose of the work altogether.

Normally, the trigger simply connects to the sear. Pulling the trigger moves the sear out of its notch, releasing the spring-loaded hammer
to strike the firing pin which in turn strikes the primer; or the coilspring-loaded firing pin directly. Other, often-Germanic systems have their own
miniature lockwork which, when cocked, allows an exceedingly light trigger pull to discharge the firearm, a setting that would be perilous to carry in the field.
