The 9mm is having something of a renaissance these days. Although maligned in the past due to its inability to reliably deliver incapacitating force, recent technological developments in bullet and propellant design have move the round back to the forefront for many LE departments. With its lower costs, lighter recoil and now more capable on-target performance, the 9mm is a force with which to be reckoned.
Read on to learn some specifics on why.
1. Shootability: While some shoot the .40 S&W well, few shoot the 9mm less accurately. Those who have problems using the .40 S&W almost always shoot a 9mm more accurately. This is true at any distance and even more so when repeat shots are needed. Shot placement is the most critical factor in stopping the threat, and the 9mm does nothing but enhance that ability.
2. More Guns: These days, there are more 9mm pistols available than any other, allowing officers to get just what they need to fit their hands. Agencies have more choices and officers can choose a pistol they like (where policy allows) — all of which translates to more practice on the range and more confidence on patrol. Most major companies make 9mm pistols in duty configurations that will fit just about anyone.
