It's alright, a little low on power as standard, but fine for paper punching and if your PCP power is OK on a standard reg you should get similar power from CO2.
I thought about this for my Twinmaster Top, but given that it's a target pistol and that it would be unfair to put it up against a Umarex the in the CO2 Target Pistols now go in the same comp class as other PCP target pistols.
