I've used this pen every day for about a month now and have no wear on it.
Same here and my 1912 has been the only pen I've used at home since getting it in early August. It's therefore been capped and uncapped many times.
I think you need to take care when capping/uncapping the pen as I can see how it would work. If you do it quickly and bring the cap to the pen at an angle it will catch the barrel. I keep the fingers on one hand at the end of the cap and the other hand on the pen. Mi ensure that they met head on and the fingers on the cap guide the cap onto the threading with no contact with the barrel.
