For over two years, I've been using the 3.1mm wide FS that came with the pistol, just replaced the red fiber with a green one to help my ageing eyes. I would like to try a narrower FS, but have to keep it IPSC Production-legal. What are my options? I'm not sure if every sight I see on CZ Custom will meet IPSC requirements, I thought I could only use sights manufactured by CZ. The have a 2.75mm wide FS available.
Another question: I tried to measure the FS height using a caliper, but without removing the sight, and came up with a reading of 5mm. Is that even possible? On CZ site, the shortest sight I can see is 5.25mm. And on CZ Custom, the shortest sight is 5.5mm in either 2.75mm or 3.1mm widths.
TIA.
