Short Perdator P3 with Uni-Loc Black Collar? Or other?

[Mr.RS4]

Short Predator P3 with Uni-Loc Black Collar? Or other?

Is there any shorter length of back part of Predator P3 cue?
I have Uni-Loc Black Collar on my Z2 shaft(w/Uni-Loc Black Collar).

Or is there any other good half back cue? That could fit on my Z2 shaft Uni-Loc Black Collar?

Need about 115cm same as 45.27"

If there are any ajusteble from 40 to 50 inch, that would be great

 

[Mr.RS4]

Are there not anything to use with my Z2 shaft(w/Uni-Loc Black Collar)?
