Pa6-cf vs pla+ dimensional accuracy

Every thing i print in pla+ has been pretty dimensionally accurate on my K1c. However when i print the same thing in pa6-cf. (all fillament sunlu) the dimensions end up slightly smaller and the tolerances are arguably too tight. Magazines dont slide in and out easily, mag catch barely fits and wont slide. Pin holes are too small. Etc.

How would i address this. As it seems filament dependent not printer issue
