So addendum to my earlier comments, I received this pen early in 2018 as a birthday present and have been carrying it nearly constantly. However, as I didn't get it from massdrop, I can't add this in the reviews section.
I have two Karas Kustoms Bolt pens, and the action on the brass Bolt is way smoother. It's hefty in hand but not cumbersome, and the bolt action is easy to use. The Fisher refill writes well, but I'm going to change to a different cartridge when it runs out as it's kind of "sticky" when I first start writing for the day. The oval shape of the barrel took some getting used to, but I really really liked it after a few months, and I'm carrying this pen more than my other fountain or ballpoint pens. I always get compliments when I use it.
I carry the pen in my back right pocket, and in May or June the clip got caught on a duffle bag strap and snapped. That would be my only complaint of the pen, is that the clip isn't super robust around the screw hole. However, I contacted Boker's customer service and they replied within two hours and sent me a replacement clip (with a torx allen wrench in case I didn't have one) which I received within 48 hours. I'm pretty satisfied with that customer service.
In case my tale didn't have enough ups and downs, I was at a friend's cabin at the end of June, and took all of my EDC items out of my pockets while I napped in my hammock. When I reloaded my pants, I somehow missed the pen and it laid there for a solid month before I was able to go back up and look for it. It was out in the rain, sun, and (presumably) was run over by a riding mower a few times. When I found it under the trees, it looked practically identical to when I'd lost it a month before. There was a little dirt in the mechanism and the pen refill had a little bit of surface rust, but after a quick wipe down inside and out it's back to new.
I've seen other reviewers saying that the top has come lose, but I haven't had that happen in a solid half year of use. I will agree that there's a little bit of wiggle room where the pen protrudes through the brass, but that hasn't really bothered me. The only other note I have is that the brass has been coated with something, so it hasn't taken any patina except for where my phone has rubbed a bit off on one corner. All in all for me, a favorite of my pen collection and I highly recommend it. However, again it's cheaper on other sites.
