Our dept. furnishes rechargeable Maglites that work pretty good. I carry a light of my own for backup, a military design shaped Streamlight Survivor LED.
I've got a rechargeable Maglite, but had to pay for it myself.
It's a good light, but as plott said we like smaller these days!

Just to set the record straight regarding flashlghts for law enforcement.
There is no one perfect light out there, everybody chooses what works best for them. I've got a Streamlight Stinger that works well for me. It's got plenty of light and is small enough to carry and use at the same time your handgun is drawn.
Surefire makes one called the Defender that is really good and several guys I know have that one. I may get it one day or the Browning Tactical Hunter, Huntmaster. I've never seen that one used by police but a friend had it this past deer season and it lit things pretty good too.
Not to big and plenty of light and you can buy it from places you can return it if something goes wrong and KNOW you won't have to worry about someone taking your money and running.
