Recently purchased a set with the black serrated rear and front tritium to replace the stock Siglite night sights on my P320C. The gun was shooting way too low with the stock sights, below a "combat zero". It was seriously frustrating and making me rethink my recent purchase. I swapped the sights out and could not be happier. Nice clean sight picture, just enough daylight between the rear notch & front blade to easily pick it up, but precise enough to maintain good accuracy. After install, the sights were dead on from 7-25 yards, using a top of the blade / center mass hold. Very pleased with these, as usual.
