Everyone has an opinion - - etc. So here's mine. And being a so-called magnet for return fire is low on the list for me, actually.
First, never mount an optic sight on a handgun. Learn to shoot it accurately using the iron or maybe fiber-optic sights that it came with. If we're talking fighting handguns, and we are, you will never have time to figure out where that sexy little red dot goes, I don't care what anyone says about it. Maybe on rifles (and I use them on tactical rifles) but never on handguns.
Next, once you have mastered accuracy, learn to shoot in low light conditions and it you want to use a flashlight of some kind DO NOT mount it on your weapon. Don't hold it next to your weapon, either. Forget the TV cops. Learn to hold that flashlight in your offhand, high and away from your face/head/body, and get a flashlight that shuts off when you release the power switch. Then you can quickly ascertain the situation and get down to business, even dropping the light if that's useful to getting into action.
Next, again, once you have mastered accuracy and understand low light shooting, from 3 yards to 15 or more yards, learn to point shoot. Chances are you'll never be in a long distance gunfight so aiming is for fun, not for fighting. Again, if we're talking fighting handguns, and we are, it's usually up close and personal and center of mass is what matters. If you have time, practice the Mozambique drill, two to the body, one to the head, but remember how many rounds you have available in case of multiple perpetrator targets.
If you're under threat and use a light correctly you're not a real magnet but if you're under threat and know what's going on you're probably not going to need a light, anyway. Police need lights to clear rooms - the rest of us do not need to clear rooms.
As noted, my opinion, everyone has one, and everyone has one of those other items in the cliche' as well.
