CZ also zeroes at 25m.

Any case I prefer to shoot 12 o'clock. Or this is what old timers called it. So POI will be just above POA. 1cm or 2cm. Both fine. But thats my preferred way.

Also remember if you change the sights to have your POI and POA on same spot wher eyour currently shooting.

You will have a small issue when you change ammo or bullets.

As different ammo in same handgun have different POI.

Just for example. These 2 videos show how ammo change also change POI. So before you adjust for your current setup.
