Perfect fit and function on my gen 3 glock 17 - AmeriGlo Glock Front Tritium Night Sights, Pro Glo Orange

I've ordered two more sets inasmuch as these sights give you the best of both worlds. The Pro Glo orange front sight is highly visible for daylight shooting and coexists nicely with the rear circles. But since the front sight also has a tritium circle insert, you have a fully functional set of night sights. While a fiber optic front might be brighter during the daytime, you lose night time capability. Unless you're shooting a strictly daytime competition gun, these are the sights for your Glock.
