Hiya dxs435 and thanks for your thread. My tactical was one of the most accurate out of the box I'd seen with my cz's so agree its a great shooter. Mine just had factory night sites ,with a front fixed and the rear basically fixed. Suppose with a sight pusher it can be moved left and right.But to elevation adj,nor windage. And assume as a tactical its design is close quarters use and most of my shooting was 7yds and closer, it was perfect. If I practiced further out shooting I'd have to just move my front dot to adj for the distance, don't know if that helps.
I never had the need to figure out if I needed or could zero my tactical, and assume its prolly zeroed at bout 7yds, perhaps some operators could suggest if re zeroing between 7 and 15 yards might have any advantage to you and POI. I recall a pistol instructor trying to explain some rise and fall of just 9mm ammo of the factory loads, adding that air temp and even the elevation of where we are at factor in. Generally at 25yds rise is +1.9 inch,50yds +2.9 inch,and -1.7inch at 100yds. For a fun project borrow a rest and notice the difference in sight picture at 15yds verses 7yds. Be well.
