Recently bought a CZ 75B SA (it came with an old Kadet kit too!) and absolutely love it - but I'm not a huge fan of the stock sights. My favorite sights are Ameriglo Protectors (matte black rear, bright green dot up front) so I went to order a set for my CZ...lo and behold, Ameriglo doesn't make sights for the CZ 75.

So I've been trying to figure out which sights I can get that can match
that sight picture as much as possible, and think this may work:
-
CZ Custom short tactical rear sight-
CZ Custom gold tritium dot front sight, 5.5mm height
My concern is that the front sight might be too thick for the 0.125" wide notch in the rear sight. How can I make sure it'll work before ordering? (I'd measure the Ameriglo sights I already have, but...sold those guns to fund this CZ. Oops.) I tried using the sight calculator on Dawson's website, but just ended up confusing myself. The ammo I typically use is 124-grain NATO-spec Winchester, but sometimes shoot whatever cheap 115gr ammo is on sale.
If it turns out the front sight I want is too wide, are there any other good options I could go with? I really don't want a fiber optic front sight, I'm not a fan. Thanks for the help!
