Antal , Skanakar and Hans Standl's books are about 25-30 years old and have not been significantly updated since first published. If you are looking for a pistol shooting book, then MEC's "Pistol Shooting - The Olympic Disciplines"
is really the only game in town.
What's that I hear you cry "£34.00 + p&p for a book!" Just think for a moment how much you paid for your pistol. It is a really good book, the pistol equivalent of "Ways of the Rifle"
