POI is below my POA. (emphasis on "my")
Because I'm not in love with the gun and am fairly likely to trade it away I'm reluctant to file the front sight. I sent CZ-USA an email giving the height of the front sight above the slide I that measured, asking if they had shorter front sights, or if not, could I buy a spare to file down.
As I mentioned, there has been no reply to the email sent to the address they have listed on their website in nearly a month. That doesn't inspire confidence in CZ USA.
Nor do the threads I've read here about other's issues getting parts over the past several months.
The other guns I shoot frequently are a Ruger MkII, a MkIII, 10/22, and a Glock 34.3
I was very surprised when Ruger performed free repairs on the 20+ year old MkII & 10/22's that I got used, with ~10 day turnarounds. I assumed other firearm mfgrs would do the same.
