Patrick McNamara (often referred to as Pat Mac), has been long been engaged in the firearms and fitness training, and his resume includes U.S. Army special operations and many years of competitive shooting. His training focuses on proper marksmanship, physical fitness and using your firearm in YOUR context.
T.A.P.S. is short for Tactical Application of Practical Skills, and is properly named based on the content. While it seems that this book is often geared toward military or law enforcement world, it has a great deal of value to the armed personal defender. Some of the gems of T.A.P.S. are proper sight alignment when presenting the firearm. His view is that it is proper to slow the presentation at the end, focusing on getting the proper sight picture every time. Another point he makes is that it is good to add stress to your training by wagering on your shooting or attending an organized shooting competition. He even addresses the pitfalls in force on force training and how certain methods can hinder proper mindset. The last portion of the book is courses of fire to make the shooter more proficient.
Overall this is a book full of good information. The drawback is that it appears that the book was not well proofread. There are numerous grammar errors and sometimes it appears that the subject jumps from point to point instead of being a more linear line of thought. That being said, this book is well worth reading.
