I do not have lasers on any of my firearms. I do see some of there advantages although I still opt for using sights. If you are new to shooting I would definitely get use to using sights first. Once you become proficient, then get the laser if you really want. No insult intended, if you are not new to shooting.
I use Glock night sights on all of my Glocks. I like them better than the trijicons that I use to use. The front sights jumps out at ya a little more. I believe that the stock Glock sights are Meprolights.
