Hey guiz! First question. Can't know everything, right? Anywho, I am interested in ONLY changing the front sight. I don't have the time, or energy, to deal with installing and zeroing the rear sight. I don't want to change my Glock too far from factory and I am not going to pay $100 for the tool, or send my Glock to some gunsmith to "hope" he does it right. My question is, if I bought a FRONT night sight only, which one would be the exact same specs (h x w) as the factory front? Or should I just order a steel Glock front sight and call it a day? Regards, Vin.
