Thought it might have been looked in very nice condition, I've had a few over the years from CP1, CP2, CP3 and my favourite although rather odd looking CPM1, loved the balance and shot it superbly, the issue I think is that PCP has been around for a bit now and early Steyr LP1's, Morini 162's etc can be got for around £400 and with most clubs having a fill bottle these seem to the choice power method, It does however mean that new shooters can now get top quality match pistols for very little money now which can only be good for the sport. (if they're prepared to go the C02 route, personally I never found filling them any more effort than a PCP)
Good luck with the CP3
