I am new to this forum and this is my first post. I hve just purchased two new Glocks, a 19 and a 23, both with night sights. Neither has been shot yet but it is my hope to make them my every day carry guns. These are my first Glocks and I'm looking for suggestions that you would make to these pistols to make the as reliable, accurate and shootable as they can possibly be. Would also appreciate your recommendation on who you would have do any of the customizing work. Thanks for your time and interest in helping. Jim L.
