Retired LEO here fwiw. I've used both flashlight and handgun/shotgun/rifle mounted lights for duty. Mounted lights are the way to go for things that might do you harm in the night. Force on force with strobes your eyes are attracted to the strobe if you are down range. However if things go wrong its likely bad guy is just going to shoot at the light whether using strobe or not in order to break contact or end you. That said I have a Olight PL-2 Valkyrie on my G17 and Ruger SR-556. 1200 lumens. A TLR-6 with laser on my G43. If you do this for a living Surefire is a no brainer and buy the best you can afford. If your not kicking doors its hard to go wrong with many of the lights out there today.
