DEFINITION

Classification: 89/132

(under subclass 125) Guns where features of the firing mechanism are claimed as a part of the invention.

(1) Note. The firing mechanism includes the firing pin and the mechanism for controlling or actuating the same (e.g.,

trigger, sear, etc.). Where the breech block and its controlling or actuating means are claimed the mere statement that it carries a firing pin will not cause classification in this or the indented subclass.
