Ameriglo’s Protector series are an excellent choice for concealed carry and personal defense applications, and offer faster front sight acquisition. The front sight is composed of a tritium ProGlo lamp (with either a LumiGreen or Orange outline), and the rear sight features serrated rear notch which reduces glare and offers assistance for one-handed slide manipulations. This configuration allows the shooter to concentrate on the front sight blade for faster target engagement.
