Sight mods For the 75B

[MisterEd]

Anyone ever had a standard dovetail cut in the front of a CZ 75 slide for different sights?

[ammo dave]

I suppose anything is possible; but the longitudinal dovetail you have now would at least be partially visible after you cut the new dovetail transversely across the slide.  Are you looking for a taller or shorter front sight?  Taller sights are available from CZ and several aftermarket suppliers.  You can make a shorter front sight by just carefully filing down your existing sight.  Have you considered an aftermarket adjustable rear sight with a matching new front  (probably cheaper than milling a new dovetail into your slide).

Have had it done on pre B guns.
but you can do most anything with front sight choices available on the "B" model guns
what are you looking for?

Thanks for the replies.  I am looking to bring point of impact up but I cannot imagine CZ having a front sight any shorter than the one that is on my 75BD as the 'dot' in it is almost sitting on top of the flat of the slide top with very little metal above it.  Also I simply want bigger sights so possibly a new front with an adjustable rear may be my best approach but I am getting confused with all the choices.  I thought I had it narrowed down with the green/red hi viz setup but then I saw how tall the front was when seeing a picture of them on a 75.  Anyway please add to my confusion with any known, good suggestions.  Thanks!

I am going to try a Dawson Precision 019-130 0.175" tall by 0.100" wide front with an LPA TPU57ZC07 adjustable overhanging rear on my new 75B.  Should be here next week. 

I have a similar setup on my SIG P226 and it works great, just looks a little weird.

If you want you can get  taller factory rear sights for your 75bd. The rear sight is numbered underneath. If you knock it out you can see the number. It is probably a #4 so you could go with a #5. Cz custom also has some nice sights.

How low is the gun shooting?  what load?

as 1steelshooter suggested, knock out the rear and check the # on the sight.

[MisterEd]

It is grouping about 3" low regardless of the load - I tried three yesterday, 100 gr JHP,  115 gr, JHP and 125 RNSP and the three targets I used could be copies of one another - except the 100 gr JHP bullets grouped much tighter but still low.  The target below is with the 100 grain JHP.

You don't state what your range was but the sight correction required is simple math.  Assuming you were shooting at 50', the sight correction for being 3" low is to raise the rear sight .031" or lower the front sight .031".  FWIW your stock front sight is .21" high (measured from the bottom of the dovetail) and your rear sight is .33" high.  The formula is :  amt of error X sight radius divided by the range  = sight correction needed (all measurements in inches).

[MisterEd]

Range was about 20 yards but I have since discovered the LPA SBR sight set for the CZ 75and I think I am going to give them a try.

Here's a formula for figuring out the sight you need. http://www.dawsonprecision.com/images/Instructions/FrontSightHeight.pdf  I'm pretty sure the cz sights are.010" are different in height each number you go up.  Mark
