First let me say thank you for letting me in. Second let me thank you for helping me to get a new last handgun that I promised Mrs. Protector I'll carry until the last dirt is thrown in my face. Third and probably foremost Please be gentle. I have several questions. Former Deputy Sheriff and US Army and still current range instructor for State of Florida Police Academy. Not new but got my new 45acp FN pistol this past Monday and looking for laser sight for home and swamp defense. Thanks again for any help even it's wrong.
