What is the "Pencil Test?"..What Does It Tell You?..(Revolvers & Semi-autos)
The pencil test, or dowel rod test, is a simple yet effective method for inspecting firearms without firing them. It can identify barrel obstructions like lead buildup, check for cylinder alignment issues in revolvers by feeling for snags, and verify firing pin function in semi-automatic pistols by observing an indent on the test rod. This technique is crucial for basic firearm maintenance and safety checks.
