If I recall right you can use standard 75 adjustibles. But don't see why you couldn't get them milled to lpa. I really like Cz custom fibre optic cOmbat set up there close and with file and brass punch its a tack driver. I shot my four staples off target yesterday with less then a mag. At 15 ft. The last adjustibles I had were on a Kimber eclipse target. I liked them but can acquire target better with this setup w green fibre. I think it shouldn't be a problem milling the slide but smecky and Stuart on here should both be able to help you with depth measurements if you are doing it on a mill. They both may have a set for you without milling. Cajun gun work and Cz customs.
