I fully agree with AC. Keith, Skelton, and Jordan wrote classics, and whether or not the information is dated is debatable. The trend now in handgun hunting, and with some in self defence, is going towards the heavier bullets, including cast, and Keith was preaching that from the 30's until he passed away.
There are books by Cooper, Askins, and Ayoob which also have relevant and valid information, but also each can be a little overly opinionated on certain issues (IMHO).
If you like the Browning HiPower/1911 tyoe of oistols, Duncan Long's "Powerhouse Pistols" is interesting, and Layne Simpson's 1911 book is by far my favorite on that fine weapon.
