Will a SP-01 upper work on a 75B steel frame?

[I Have A Dream]

Just as the title says, I was wondering if it would work on my 75B frame.

Any helps would be greatly appreciated!

I can't think of any reason why it wouldn't.

Can't remember for sure. I sold my 75B when I got my SP01. But I believe I played around and put it on my 75 frame.

Tried my 75B slide on my SP01 frame, it would have required some metal removal to function smoothly, so I stopped there.  I figured if it was too tight that way, it would be too loose the other, but I never tried and you know what happens when you assume things.

Might be a "depends on the individual guns" kinda thing.

The 75 shadow uses pretty much the SP-01 upper just without the firing pin block on a 75SAO lower.

Now the 75b and the sp-01 use different sear cages which could cause some interface with the slide but that can be fitted.

^^^^^ yaaaa.... that's what I meant to say....

If it doesn't fit, most of the time its tthehe slide hitting the ejector housing.
some fitting or changing parts will help.

Once I tried my SP-01 Shadow upper on my 75B Stainless frame and it worked fine. I even shot it that way. Bear in mind mine are both European original factory guns bought in Europe. Something from CZcustom might have some differences . I do not know. 

All ll I had to do is remove the Firing-pin-Block lifter from the 75B frame ( as the Shadow does not have an FPB ). You can do this by buying the washer from CZcustom or cutting up something yourself .  It is just a spacer to fill in the blank. Does not see any heavy wear.

The other way round will not work ( Shadow frame and 75B slide ) because the Shadow hammer is wider than the standard 75B rear  slot , also it will look ridiculous on the Shadow full rail.

This is the standard Shadow,

All went back to the originals. This was just an experiment. But it worked fine. I also tried it after modding the 75B frame to SA only and worked fine as well.
