Hello everyone, I have been browsing this site for a while obtaining great information from every ones facts and opinions. I just purchased an xd in .40 with the 4" barrel and so far enjoy having it. I would like to mount a light and possible laser on the pistol, but am unsure of which one functions best for the cost. I have not done much investigating on different lights and thought I would see what you all have on your firearm. I think a light is a worthwhile investment on something I plan on having forever so I dont want to go to cheap, but also dont want to break the bank. Also, I know nothing about red dots, but is it realistic to have a laser on a handgun and make it accurate? If so, how many yards do these usually work for? Thanks for any replies... I hope that this is not to long of a post.
