Here's a pretty funny "I hate CZ" story from the other day:
A buddy I shoot with pretty frequently, and who is a good shooter, brought his Sig P226 Legion SAO to the range. I brought my slightly modified CZ SP-01 Tac.
He asked if he could try my CZ. He shot a few rounds with it, and I could hear him muttering. He put a fresh target up with two 10" circles right next to each other. He shot 10 rounds into one of the circles with his Sig and then 10 rounds into the other circle with the CZ. The difference in groups was noticeable, even from where I was standing. "Holy ****," I heard him say.
"Ok, I need to do this again, so I know it's not a fluke." He set up the same situation again with fresh targets. If anything, the CZ group on his 2nd round was even tighter. And keep in mind this was a gun he had never shot before, versus his Sig that he's been shooting regularly for months. "bleep it, I'm shooting better with a gun that cost half as much."
On the drive home he had already decided he's trading in his Sig and he's in the market for a CZ Shadow II now...
