Laser opponents make me laugh a bit. Most of them have never seen a laser in use, let alone actually tried to use one. They are excellent at giving out non-sensible advice on them, though, and it often contradicts other principles that they adhere to in their CCW pieces. Let's look at the arguments:
1. The laser gives away your position in low light. This one is really funny to me, especially if you agree that the target must be identified as a threat before engaging it. Since we all agree that a laser's use is in "low-light" situations, how do we identify the threat? With a light! Nearly everyone will advocate a good flashlight for this use. I guess a thin beam of red light is far more efficient at revealing your position than a big solid white one! CT lasers are activated and deactivated immediately simply by relaxing your already natural hold on the grip, a fair sight quicker than activating and deactivating a flashlight! If there is enough light to identify the target and use irons, the laser simply co-witnesses with the irons. Again, no disadvantage at all.
2. Your typical gunfight is xxx and happens within xxx amount of time, negating any effective need for a laser. This argument is probably the most hypocritical you will ever find on this site. Does anyone here actually plan for a "typical" gunfight??? According to the "typical" gunfight stats, if you carry a gun with more than 3 rounds in the chamber, you are over prepared! If you have a BUG, you are over prepared! If you use night sights, you are over prepared! If you even carry a gun at all, you are over prepared! Many who call out a person on this site for not selecting a large caliber, high cap with night sights will do so with the argument "what if your fight isn't typical". This is a good approach! So, how many of you are not good, but deadly proficient during an adrenaline dump in the dark? A laser will help you get there. How good are you when you've lost the ability to lift your gun all the way to your eye for the irons? What if you are laying on the ground being beaten? What if you have a cover source that allows you to reveal only the gun while still being able to see the target? What if you could hit the BG without ever having to expose the top of your head? Lasers can help with all those things. You may never need one, but that doesn't mean you can't benefit from one, and in some situations, it may be the one thing that allows you to survive when conventional irons might get you killed. Sounds an awful lot like why CCW holders actually cary in the first place.
3. You must master irons because your laser can fail. You should master every way of shooting your gun, but does this mean a possible failure of a device means it shouldn't be used??? It's a foolish argument! By this logic, you shouldn't use a semi-auto gun, as it might jam. You shouldn't put an optic on your rifle, it might fail. Of course, anti-laser folks already ignore the fact that basic irons fail every single day! Failure is built in to the iron sight by virtue of the fact that once it gets dark, you can't see them! This is why night sights are so popular! Of course night sights fade over time and may become too dim to actually see well, too. Maybe we shouldn't use them, either? Ironically enough, in our defensive carbines, most owners buy a non-magnified red dot for quick aquisition for defense (including the military) for simplicity and effectiveness, but we shouldn't apply a similar philosophy to our CCW? Preposterous.
4. Lastly is the suggestion that a laser is a distraction in a gunfight and puts your eyes on the threat instead of the defensive tool. This is possibly the most idiotic argument out there. The dot goes where the gun is pointed. If you are pointed at the target in a conventional manner, the dot is right in the line of sight. The laser is BRIGHT! It doesn't take five minutes to figure out where it is. In low light it really is picked up instantly. Additionally, in what world is it advantageous to not be able to sight in on a target while seeing what the target is actually doing? It is always a tactical advantage to be able to clearly observe the threat as a primary focus and respond to it dynamically. A laser allows that, irons allow you to shoot at a blur while you focus on that front sight...what is that blur doing? Of course, much as our carbine defensive users have learned, limiting the number of items you have to line up to be effective is always preferable for defense. They use red dots first, with back up iron sights! The laser clearly wins here.
5. Lastly is cost. Simple one here. How much is your life worth? We all agree that training is important, but if you can swing hundreds/thousands for good training, is a $200-$300 investment to give an additional edge really wasted money? I think not.
The laser provides an additional potentially life saving tool to your carry piece for a reasonable amount of money and I have yet to see ONE good, logical argument against them. They are amazing training tools, too. Get one, learn how to use it, and be safe.
