I have to agree with a45gunslinger. It is very hard to get use to the laser bouncing around and people concentrate on it more than the target. Sure in an indoor range and no pressure is on you it is manageable, but in a dangerous situation the last think I would want is to think, where is that red dot at. Get the gun and use the best thing it comes with, open sights.
I have tried the laser and I for one think they are not a good as advertised. Also hard to see in daylight.
