Shot at an indoor range yesterday. The sights performed well. I'm off to the left by about an inch at 15 yards. Should be easily fixed, but at self defense distances they are fine as installed. I like the visibility of the front sight, really helps my aging eyes focus in on the front. I was concerned that the front sight width might be a little wide, but that concern was unfounded, it's just about perfect for me. I'm satisfied with these, they are a nice addition.
