help with Different joint types

[Fishbone]

I have a Fury DL 6 and a Fury DL 10 but the joint pins are different. The shafts are'nt interchangeable. My DL10 joint pin looks like the picture of a radial pin.
Anybody got a picture of a tru-loc joint? what gives? Any help appeciated

If they are different then someone sold you a used cue. Every fury cue has the same exact joint
