I bought a brand new AA Contender during the short time when TC was making them and could only at the time afford one extra barrel over the one that came on it.
So I started with a 10"/.22 and a 10"/.357.
Over the next few years after the AA was discontinued, I managed to find the rest of the barrels I wanted, all NIB and all original AA in 10".
So all 10" and in AA, I'm stuck with:
Being all original with all the boxes, I haven't the heart to do the simple mod for using other barrels with it, so I need to pull the trigger on getting an older Stainless frame and then start chasing down the other calibers I'd like.
It's always something...
