This is a great book and I have read it twice and keep referring back to it several times each year. Especially the last 7 years on the job when I worked the Surveillance Unit.
Jim Cirillo liked, very much, the S&W 4546, (p92). This a a 4500 series of Smith's that is double action only. This is one of the things that got my unit using the S&W 4500 series of pistols!
Cirilo also liked the 41 Magnum on a S&W frame a Dan Wesson barrel and with his own designed and patented wadcutter bullets for it and the 44. He also liked the 44 Magnum with a 4 or 5 inch barrel double action.
It says in this book that if he were still on the stakeout squad he would use a Glock 21 as his primary gun!! (p116).
He also has a very good section on shooting handguns.
Cirillo says several times in this book that the main considerations with a handgun shooting are 1) Construction and configuration of the bullet. 2) Diameter. 3) Velocity. and 4) Weight!!! (p47).
I think I might read this book again!
