They are actual combat sights. They are known as U-Dot sights, and in my opinion they are among the greatest found on any manufacturing pistol in existence today. The front sight creates a bright, distinct aiming point that leaps immediately into the eye’s vision by fusing a tritium vial with a sizable photoluminescent ring. Springfield makes use of the wide U-shaped notch, Tactical Rack U-Dot rear sight, which rapidly aligns with the front sight.
It’s simple to get a good grip on this gun. The very successful Thinline G10 panels from VZ Grips are combined by Springfield Armory with “grenade” checkering on the front strap and mainspring housing. It is cozy yet also very “grippable.”
