Since you like action type books, how about one that is non-fiction and will make you say." that's unbelievable".
It is out of print, but you can find it though most good book stores. the title is "Unrepenant Sinner" by Col. Charles Askins. It is his life story starting in the 1920's and his border patrol career and his experiences during WWII in North Africa, and in Viet Nam before we sent in ground troops.
This guy made some of the old west gunslingers seem like pikers compared to what he did. If done today he would be tried for homicide many times over. It was in the days when law enforcement shot first and asked questions later.
He also got one of the first S&W 44 mags along with Elmer Keith and used it to shoot a viet cong while in viet nam as a advisor to the S. Viet Nam military. Nobody has contested that he was the first one to kill a human with the brand new S&W 44 mag.when it first came out. Heck! He makes Dirty Harry seem like a social worker.
If they had border patrol agents again like this one, there would be a shortage of drugs being smuggle across the border because the smugglers would end up being shot first and be given their last rites instead of their "Miranda" rights.
Get the book, you will love it.
