Congrats 5of7.
I'm sure your shooting will improve drastically with that gun.
I'd shoot groups of 5 rather than 13 for your measurements though.
That gun should allow you to improve for quite awhile.
A REALLY ... And I mean ... REALLY ... accurate 9mm load for that gun is 6.0 grains of Power Pistol under a 125 grain truncated cone lead bullet with Winchester SP primers.
I get my bullets from http://www.mastercast.net ... About $57 per 1000. Best 9mm load I've found so far.
With that gun ... And the above recipe ... You can be POSITIVE that any variance is YOU. That combination is simply spectacular ... Even better in my Sig 226.
Don't be afraid to dry fire that 75 THOUSANDS of times sitting in front of the TV too. It will DRASTICALLY improve the trigger without costing you thousands for ammo.
Please give that gun at least 2000-3000 live rounds before deciding to do anything to it. As well as 10,000+ dry fires.
After that ... I'd consider having CZ Custom install a SA trigger on it ... Or having CZ custom do a regular trigger job. I wouldn't mess around with any local gunsmiths unless they SPECIFICALLY specialize in CZ's. It might cost a small amount more to have CZ do the work, but they KNOW THEIR GUNS INSIDE AND OUT, and will tune your gun the right way.
Congrats again on that 75 ... I can't say enough about the quality and accuracy of that platform
Now you just gotta dump the WWB garbage, and watch your accuracy, group size, and consistency continue to improve.
It always blows my mind that people spend $500+ on a gun, then add $200 worth of add ons to it, and continue to shoot garbage ammo through it. They should have spent the $200+ on reloading equipment and supplies instead of crap like guide rods that do NOTHING, useless and unreliable trigger parts, and junk ammo.
Quality ammo means everything in 9mm when it comes to measureable accuracy.
