I got duty gun p07 and no complains except dar the polymer frame bend after a year of having it. Dat was the only down side. But i called cz and they said to ship it in for cosmetics.
I have the CZ P07 40. Great gun and great customer service.
I had trouble with Rem. UMC HP, none at all with fmj.
Tried Win. PDX HP and no problem with cycling. Great shooter and just seems to grow on you.
