What exactly would be considered GOOD accuracy. Below is a target I fired at 25 yards from a sitting position (leaning against the bumper of my car). It's a 15 shot group shooting 115gr Blazer Brass. This is a pretty typical group and I would like to be able to close it up if possible. The orange dot is 2" and the black is a little under 4". Is this about the limit of the MP's abilities or can it be more finely tuned to shoot tighter groups. I have been thinking that maybe with sights allowing a 6 o'clock hold since the front sight completely covers the black at 25 yards making most shots a best guess. The two stray shots in the white are the result of my own poor trigger control.
