I've made quite a few Gentleman and Statesman roller balls and have never once had this problem. I don't know of anyone else who has either, at least nobody has ever mentioned it before in the three or so years I've been around here.
I've had this happen with every screwcap model I've made, CSA or Berea. As said above, if the nib coupler isn't epoxied into the brass tube rather than just press-fit, you run the risk of it coming loose. I wish they ALLLLLLLLL would put this bit of info in their assembly sheets, b/c it's a hazard with the Jr/Gent, Emp, Imp, States, Baron, Sedona, you name it.
Seems really bad on rollerballs however--- I believe the spring inside pushing OUT while the screwcap is pulling out both work to wiggle it loose.
