I bought my P30 a year ago. I have not shot it in over 4 months now. My shot grouping is not what I expect with a 9mm compared to both my .40 USP and .45 Tactical compact both H&K. It may be the way it sits in my hand, but it is constantly low and left of my target.
I will say the .45 Tactical is by far the best gun I have shot. The recoil is very smooth and follow up shots are quick to get off. If I had to have one gun, it would be the .45 Tactical.
I have thought of selling the P30, but I don't see any reason to loose any money on it at this point. It can sit and come out and play from time to time.
