I shoot 22 bench F class go stalking, but last week I tried on of these umarex cp88 on steel plates, and although the bang wasnt there it took me back to when I was a UKPSA range officer in the 80s. I seem to have caught the bug I was thinking of getting a CP88 because they have good reports. In the spec for these guns it says the 6 inch barrel is 10 fps faster than the 4", are they more accurate than the 4", Also to start with I would like to buy a used one to see how I go on but there do'snt seem to be any advertised if anyone would like to sell one please pm me also any one with any comments on the sport or the guns will be welcome.
