I am looking to add to my firearms/mindset reference library. I have a start on some, but I was curious as to what most people think as "required" books for the library.
My last couple of purchases were:
Concealed Carry Class - Tom Givens
Strategies and Standards for Defensive Handgun Training - Karl Rehn & John Daub
Long Range Shoothing - Ryan Cleckner
Chassepot to FAMAS - Ian McCollum
Thorneycroft to SA80 - Jonathan Ferguson
The Reluctant Partisan Volume I - John Mosby
A buddy recently gave me an old copy of Brownell's Gunsmith Kinks, and I have several other old books by Jeff Cooper.
What should I add?
