Not very durable

I own 3 model 540s and 2 of them are now out of commission.

For one, the front nib plastic holder kept popping out.

The other, the end segment where the screwing pump is located, also kept popping out.

 

I have never experienced this kind of issues with Lamy, Pilot and Pelikan.

Not sure if the new model 580 has this kind of issues as well.

 

Finding this topic horribly late ....

My 580s seem very reliable and sturdy. My 580 USA Red Blue/RBT model was a pocket EDC for months--and I'd bought it on eBay, where you can't ever be 100% sure if it wasn't used first even if marked "new".

(The exception being anything you buy from FPN member Speerbob, of course! His descriptions are voluminous and truthful. I have been 100% satisfied with everything I've purchased from them.)

Nevertheless, even my 580 RBT is still crack free, several years after serving its EDC stint. 

I suspect that TWSBI simply released the Diamond model too soon and it needed more iterations in development before it was actually market ready. I don't know exactly how many months or years separate the 530, 540, and the 580 models from each other, but a very casual search suggests that it's only a few years between the three. 

As it's been several years since the release of the 580 model, I'm comfortable with assuming that the cracking issues that plagued the earlier models have been mostly addressed.
