Thanks all and you Mishu too.
This makes sense now sure I agree but no where have I heard this info before.
Is this common knowledge in the spearo think tanks?
This should be the first thing you get told when buying a Euro gun on the web sites and all! Dam!!!!
What a major pain in the ass!!!
Why the heck can’t these huge fricken companies (they make this stuff by the ton I am told now) make spear a shaft interchangeable is beyond me?
The tolerances are very very small I just found out!
The manufacturer wrote me and explained and you must have something so exact to fit this gun on the back end of the spear shaft you cant hardily believe it!

This is what they wrote and told me…..

“the tolerances of the rear part of the shafts
the part that is inserted in the cassette is at the extreme rear and in front of the trigger mechanism groove must be 4.8 mm ± 0.2 mm - the top of the shaft on this location should be flat either milled or stamped and have these strict measures.
for the part used for the trigger mechanism to hold the shaft (the 2.4 mm location on the picture) the measure is 2.4 mm ± 0.2 mm
Any shaft that does not match such tolerances should be rejected.”
