I see very few pluses and many minuses on having a laser, red dot or flashlight on a 2" carry gun that will most likely be used at close quarter distances. I have seen too many fail for one reason or another and for civilians I find that they create more issues than they solve. I have repaired a bunch of them for friends and they can not even give me a valid answer as to why they even use them on EDC's.
The company's making them have done a great job in promoting, selling and "creating" a need. Now a SWAT Cop who might have to actually take long distance shots would IMO have more legit reason to have one, but still would IMHO be better off in shooting with the basic sights on the pistol. They are very accurate for an officer who knows how to use them!
