Easy Tiger. Don't start flinging insults.
What has been said to you is simple, the pistol even at 6PFE would be totally useless even as a plinker in the back garden, you would be better off with one of those G10 repeaters, or a pea shooter.
If you lived in the good ol USA then its a different matter as you can legally have a higher power.
Airifles and pistols have thier limitations and here in the UK 9mm would be a waste of time unless you had an FAC and could get the pistol legally imported???
