I currently have a CZ 75B that I would like to change the front sight to a fibre optic sight.

The problem I'm finding is what height of front sight do I need to directly replace my stock front sight.

The pistol has the factory non-adjustable sights.

From searching there are 5.5mm and 6.5mm fibre optic sights, but I am confused on which I should get.

Any help would be appreciated. Thanks


Secondary question - I'm running my handloads, fairly light shooting 3.7gr titegroup with 124gr campro, - what weight recoil spring would be recommended I run?
 
I have one more match coming up and didn't want to remove anything until its done, just hoping someone knows and I can get the new one ordered.

Elevation is good with current sight.
 
CZ Custom offers some advice as to which height you require. Check out their website and click on specific sights to find out which may fit. They say that 5.5mm is standard height front sight on CZ 75 Factory Pistols. Where it gets interesting is the various rear sights such as CZ Target, Competition, or Shadow sights and they offer advice for each sight.

Select shooting supplies has similar info for their CZ fiber sights.

Ganderite is correct in that you can measure the sight once it is removed and them order a similar height.
 
5.5mm is the standard height front sight in CZ75 factory pistols. Now keep in mind that you can order 1 or 1.5mm fiber optic rod. I suggest you order extra fiber optic rod in whatever size you go with. I ordered extra in red and green in case I wanted to change the colour. I upgraded both the front and rear sight on my CZ75 and the difference is night and day. Amazing.

After looking at cz customs and other sights I have figured out that the 5.5mm is what I need.

Any chance the more knowledgeable guys on here know if a lighter weight recoil spring would help with felt recoil and provide faster/more accurate double taps?

Again shooting 124gr campro RN over 3.7gr titegroup.

Thanks!
 
it is 5.5mm....

If you're getting reliable function with stock recoil spring I would not go lighter, you'll get faster and more accurate with practice. Leave the gun stock just get a 13lb mainspring for improved trigger pull
 
Good morning,
I had installed a LPA combo on my (sold now) CZ-75B : black serrated adjustable rear and FO front.
The front was a bit high but it was night and day with the stock sights.
And a breeze to install yourself.
 
Are the new sights pre-drilled for the roll pin or does one still need a 2mm drill bit to do repin it yourself?

With 3.8gr TG and 124gr pill, I've shot it using an 11lb recoil spring on my Shadow 2 and haven't seen any peening on excessive wear. I did buy a backup slide lock just as a precaution.

Sights are not pre-drilled.

As already mentioned if it runs well now then leave it alone. The recoil spring needs to be matched fairly closely to the load. So you're right to ask.

You're shooting in competition now I take it. Do you encounter many stovepipe jams or failure to lock back at the last shot? If you don't get either of these other than very occasionally then your load is well within the rating for the spring that is in the gun now. Going to a lighter recoil spring is only required if you have a weak ejection path for the empties and find you are getting the stovepipe jams or failure to lock back. If you switch to a lighter spring anyway it means the spring may not absorb all the recoil energy. And that means the slide will beat on the slide stop needlessly. CZ's have a bit of a rep for snapping the slide stops as it is. And I suspect that this urge to go to a lighter spring when it's not justified might be part of the issue.

Good afternoon BCR,
I'm just back from the range with my brand new Colt Gold Cup Trophy 9mm, model 2017.
Experimented all what you mention above, stovepipes and also double feed.
Empties were flying straight in the face or ejected close by.
The pistol is hard to rack, (and I'm quite strongly built); the recoil spring is a two piece affair but I believe the main spring is too heavy so I ordered a set of springs from Wolff.
Should cure the problem.
 
I got new front sight in my for my CZ (HIVIZ had to be drilled)
