The SlantPro style rear sight is designed with concealed carry (EDC) as it's primary focus. The sight is contoured and completely snag free. The rear face is serrated and slightly slanted forward to help eliminate glare from any light source. Equipped with the legendary Straight Eight night sight system, it is a must have addition to your firearm. One single tritium insert in the rear (for low-light and nightime shooting) that aligns vertically with the single tritium front insert (when used as a set). This vertical alignment is proven to be faster and less confusing for the human eye.
