CZ Shadow 1 upper on SP-01 or 75B? Pictures Inside

[kwelhand]

Recently I was able to acquire CZ Shadow 1 complete upper .

My plan was to install it on my existing 75B or SP-01 (CZ custom shop modified gun).

Unfortunately, the CZ Shadow 1 slide wouldn't slide in either lowers.

It looks like my 75B and SP-01 slides have firing pin block and the Shadow upper doesn't have it.

 

Does anyone know which CZ lower fits w/ Shadow 1 upper shown on the pic?

Any modification I could do in order to work with my existing 75B or SP-01?

 

Sorry for the stupid question... searched the net and couldn't find the answer.

You can delete the firing pin block in your sear cage with a spacer, but you'd need two complete sear cages to switch back and forth

Thanks for your reply. 
Never thought about the sear cage.

Do you know where to get the spacer or how to install in?

Buy a spacer

Remove the block and its spring from your slide. Remove the lifter from the seat cage and replace w the spacer. Reassemble. 

 

Now your shadow upper will fit on your frame. You also will no longer have a legal gun in most divisions if you're a competitor.
