9mm making a comeback

[noylj]

The FBI has more politics in the selection than ballistics.
I have been surprised that so many believe their tests are that meaningful.
Carry what you have confidence in and let them carry what they are ordered to carry.

Maybe the (relatively) new +P and +P+ and the new High-tech HP, Polymer-filled bullets may help boost 9mm performance & thus interest in it.

I prefer to put a bit of BACON fat in the hps of my 9mm carry ammo....just in case....

It’s not that the .40 S&W failed to deliver the terminal performance they wanted. It’s just that the new breed of 9mm ammunition can deliver similar performance without the generally snappier recoil and the accelerated wear (on both pistol and shooter), at a more affordable price. The fact that the new pistols can house more of the cartridges in the same sized gun is an added bonus.

These agencies have also taken an honest look at the demographics of their personnel, and have accepted the fact that law enforcement officers no longer come in just one size—Large. Instead, there are many officers with smaller hands and shorter fingers who find it difficult to reach the controls on larger caliber pistols with their corresponding larger frames.

Despite all the ergonomic advances in pistol design of the last three decades, there is no way of getting around the fact that a .45 ACP pistol (and particularly a wide-body .45) is just going to be bigger in the hand and a .40 S&W in a smaller frame is going to recoil more.

A smaller-frame pistol in a milder shooting caliber allows more officers to achieve the control necessary for good shooting, and makes sense for diverse agencies that want to standardize on a single gun and caliber.

The FBI’s renewed interest in the 9mm doesn’t indicate that other cartridges are less capable or that they are poor choices for law enforcement. The truth is, with modern ammunition, any of the calibers currently in use by law enforcement will do the job — yet none of them will turn a handgun into the Hammer of Thor.

Sounds like a logistics decision.

Cheaper ammunition. More volume of fire from larger magazines. Reduced wear on handguns and "common caliber". Street patrol people with full sized handguns and detectives with compact handguns can share ammunition.
