just wondering... why don't they make a blue laser weapon sight? is it not practical? it is my understanding that green is more stimulating to the eye, i guess is how you would say it. but is blue not more powerful and more visible during the day? it is also my understanding that red lasers are a diode type as green is crystal, which makes them more sensitive to shock. is blue also made this way? sorry if this has been covered or perhaps i'm on wrong forum. just didn't expect many people on a gun forum would know much about lasers. and sorry if i don't got my facts strait, i'm very new to lasers other than buying a pointer here and there lol ><; any input would be much appreciated.
