Do you know it's the gun and not you?
If you know it's the gun, what is different between the P01 and the PCR?
Trigger?
Sights?
Grips?
Do you shoot the same ammo in both? Have you tried different ammo in the P01 - because sometimes some guns "like" different ammo than what works well in some/most other guns, even of the same model/caliber.
ID what is different and work to change it. I've seen (I own) CZ Compacts that benefitted from the CGW barrel bushing. I know the triggers benefit from some polishing/stoning of trigger bar, hammer strut, some other parts. DA trigger pull is supposed to benefit from lighter springs.
Good luck with it. It's tough liking/shooting a gun that doesn't perform to your expectations. Just be sure it's the pistol/rifle that needs the work and not the ammo or the shooter.
Not trying to say you "can't shoot", just saying I've seen people spend lots of money on high dollar rifles and scopes only to go to the range and see some kid (that's right, a 10 to 12 year old, boys and girls both) out shoot them with pretty much standard rifles with nothing special about the rifle/optic. It's a shame when people attempt to buy good groups vs. skills improvement.
