I am milling my own dovetail, I have a mini-milling machine. I found a really impressive fully adjustable sight; it fits the Springfield Armory Custom Shop 1911's and is made by LPA. One of the best looking sights I have ever seen. Midway USA has them for around $45.00, what a bargain for this sight.
I orginally cut the sight base to keep from removing so much metal from the slide, but I have decided to go ahead and do a full Noval cut on my 75/.40. The full depth of cut is .230" and I cut down to .205" this evening. I plan on doing the final .025" tomorrow evening then make the final 65 degree cuts.
I don't know if anyone has ever done a full Novak cut on a CZ, so I decided to find out if it will work. I called Novak sights and the guy I spoke with said he couldn't ever remember doing a CZ-75.
I think this is going to be a fantastic looking sight on a CZ. I'll post pics when I'm finished. I may do my CZ-97 if this turns out as good as I think it will.
LPA makes a sight that fits the stock CZ dovetail, but it doesn't look as good as this Springfield Custom unit. Besides, there are tons of different sights for a Novak cut.
