Please can anyone that knows share the detent ball diameter used in these two models?

I presume they're the same size. I know they're larger than 1.5mm because I can see this by eye (got a packet of 1.5mm ball bearings and cam see they're too small).

My guess is 2mm.

They're all getting flat on my knives and id like to replace them with ceramic equivalents.
 
I have replaced the detent balls in a couple old PM2s with 2mm ceramic, but you need to widen the hole in the liner a little bit to fit, so you need to be committed.

I'm not sure of the factory detent ball size.
 
Must do with the models I have as this is happening on a few of them - it's impacting their performance.

On my Maxamet para 3 it feels stiff to open and close now. I've polished and oiled the washers and adjusted it to be as loose as possible and still having this issue.
