I'm kind of reminded about a guy that told me he wanted to go to scuba school, but didn't know how to swim. He figured that if he could breath underwater, he wouldn't need too.
There are different tactics and techniques for using lights and lasers dependent on the scenario. You are allowed to add all the lights, lasers, comps, spikes, and doodads you like.
My advice is first learn to operate your weapon safely, then learn to shoot accurately, then you can add speed, scenarios, and fancy black ops gear.
And always practice good shooting etiquette.
Wow, lights and lasers are "black ops" gear? Comparing normal people to a very stupid scuba student? Piers Morgan, is that you?
You seem to have a persisting opinion that anyone with any kind of tactical attachement on their weapon is automatically using the it as a training crutch instead of practicing, is a disastrously poor shot, doesn't have range etiquette, is unwilling to practice... in other words, a range ninja???. That smacks of elitism towards your fellow gun owners don't you think? Is it even possible that people who have a practical-tactical attachment on their weapon could still have good etiquette, are trying very hard to increase their skill, will practice as much as time and money allows, and try their best to understand science behind their tools? Is it also possible to do things concurrently? Can't I have a pistol with a laser at the range (without using the actual laser, yes I know) to practice proper technique and etiquette while maintaining the total weight of the weapon? If I ever have to use my firearm in self defense, my guess is that it will be in my home, at night and the lights will be off. Are you suggesting that I should not even consider this scenario since I am a newbie? Are you also suggesting that I should not use every advantage that I can, like a light or laser attachment, that will make hitting the bad guy easier? I can't agree with that thought process.

I am splitting hairs with this next point, I know but, the term "fancy black ops gear" sounds like you are trying to stigmatize tactical attachments, kind of like how some people use "assault weapon" and "military style weapon" to scare people away from the AR and AK. Bad juju there.
Please note, if someone actually waves thier gun around at the range, never practices, ignores range etiquette then, by all means, let's call them "range ninjas". It really has nothing to do with what weapon they have in their hand and even less with what they have attached to it. I look at it this way - would I rather have A) an a-hole point his unadorned pistol at my head at the range or B) an a-hole point a pistol with a light at my head at the range? Neither A nor B actually. The flashlight just below the barrel I am looking down doesn't really make it any worse.
