In the past year we have made an extra effort to increase our line of handgun sights. First we have redesigned our rear sight by reducing the diameter of the LitePipe from .070 to .050 inches. This smaller diameter prevents the rear sight from overpowering the front sight. We are now offering all rear handgun sights in both green and red. Rear sights are now available for most models that we only offered front sights for previously, as well as for many new models.
