A bit, but my group shooting is pretty solid with regular irons. Most of the size of initial 10 round group was wind. The biggest issue I am having, is the sights themselves. The rear notch was opened up pretty wide, and the brass front is tricky to tell where you are elevation wise if there is any light on it.
The brass front is nice in low light as you can aim with it due to the glint well i to twilight, but on light colors- like the white of the paper, or the cardboard it’s very easy to be off the edge of the black and into the paper without realizing it.
