On another approach...
When our agency transferred from Beretta to Sig- it wasn't so much a question (by the agency) of trustworthiness of the pistols as it was familiarity. I can see that- kind of a big difference between the two.
What they determined was a safe way to go was to implement a 200 draw (familiarity with new holster), a 250rnd familiarization shoot, and a 50rnd qualification.
I don't think it would be fair to say that the $$ you paid or the reputation of the pistol (loosely grouping the terms) deserves a blanket statement of "You bought a handgun- you MUST have X number of rounds through it to determine if it passes muster." You bought a CZ P07, not a Kel-Tec P11, Leinad, Jennings, etc- That said, I kinda suspect that 50 rounds ought to tell you if the pistol will work or not. And another 150 should determine if you can work well with the pistol.
I applaud the guys who have the time, $, and resources to say they never trust a weapon until they have 500-1000 (or whatever magical number)rounds down range. Truth is- you bought a pistol with a good track record, and may be hindered by having to jump straight from the Glock to the CZ without having another (or whole drawer full) of backup weapons that have a magical number of surety rounds fired through them.
In my opinion? Clean the CZ, lube as normal, squirt a box of 50 through it. If there are no major hiccups, then give yourself some time for practice draws and dry fires.
Enjoy your new CZ!
