The liberalization of concealed carry laws over the past several decades represents a dramatic expansion of the right to bear arms in the United States. Concealed Carry Revolution offers the first comprehensive but concise history of the development of these laws, from the restricted era of gun carry in the 19th century, through discretionary permitting systems in the 20th century, to today's shall issue and permitless carry regimes. It also explores variation in the implementation of shall issue concealed carry laws from state to state, especially in terms of training requirements. Brief and accessibly written, this book will appeal to experts and interested others alike.
