I have recently purchased my first glock and have narrowed my choice of night sights down between the trijicon fixed sights, or the meprolight adjustable ones. It seems like it would be nice having some that are adjustable and both brands have great reviews. One thing someone said about the trijicon sights is that the tridium have a white circle around them wich makes aiming during the day time much easier. I will be target shooting quite a bit, but if i ever were to have a break in night sights would be great to have. But first and foremost, i bought this pistol for a new fun hobby to go to the gunrange about once a week. Thanks!
