With universal CZ Shadow 2 Compact you can use red dot optics as well as professional competition sights.
And when it comes to sights, there are plenty of them. And most of them focus on sport shooting, thus those sights are fully adjustable [both windage and elevetion].
Replacing the whole sight set or just a rear sight?
Unlike most of the other CZ models, CZ Shadow 2 Compact uses the same height for factory front sight as do the aftermarket sights.
In other words, you do not necessarily have to purchase the whole sight set, you can also go solely for the rear sight if the manufacturer makes them available solely.
Fiber optic, white dots or blank sights?
This is purely up to you. However, unless you are looking for really some specific type of sights, we recommend going for full fiber optic sights [that is fiber optic rear sight and fiber optic front sight].
The most popular choice is contrast colors in the front and in the rear sight & combination of 1mm fiber rod in the rear sight, and 1.5mm fiber rod in the front sight.
Why is that? Because the front sight is further from you, the larger fiber rod does not look that much larger comapred to the fiber rods in the rear sight.
If you go for sights with fiber optic rod only in the front though, we would recommend going for 1mm fiber optic rod in the front sight as there are no fiber rods in the rear sight.
Front sight filler
With increasing popularity of red dot optics on the handguns, the front sight filler that you can find here is a very elegant solution to the question what to do with the remaining front sight.
Because once you have the optic plate for CZ Shadow 2 Compact installed, you can not use the rear sight anymore for aiming. Thus the remaining front sight would be there for no function and its better to just replace it with the filler.
Sights for CZ Shadow 2 Compact
Unlike with many other models, if you have optics ready CZ Shadow 2 Compct you still can use the classic sights, and also you can replace them.
The dovetail cut of CZ Shadow 2 Compact is the same as for classic CZ Shadow 2 models. The slide cut removes the whole part of the slide that accomodates rear sight.
Thus if you have CZ Shadow 2 Compact, you still can use fully adjustable fiber optic sights if you decide to do so.
