I love the Jesse Stone series. I've watched all of the movies. The first thing I noticed was how accurate all of the gunplay was. I mean, it's damn near dead on perfect. The stories are pretty good as well.
The first time I saw him carrying his 1911, hammer back, I pointed at the TV and told my wife "oh my God he's carrying it correctly". No gratuitous slide racking or extra clicks after the weapon runs dry. He actually changes magazines using different reloading methods.
