I have the CZ Pro-tek 1 and had ordered a custom holster for it. I also have a glock 23. The holster for the glock that I have will fit the CZ almost perfectly. The snap-down strap on the holster is just a little loose, but it still retains the gun well. As a matter of fact, I bought a Blackhawk leather holster that was made for the glock 23 that you slip down inside your waistband and it has the outside belt clip. This is not the flimsy inside the pant holster, it is made of the same type leather that regular belt holsters are made of. Fits my CZ perfectly since there is no snap-down.
