The connection is appearing to break in, I get no gap with my attys after a couple of days. Maybe the coating needed to be worked a few time on the threads to ease up. I this is now a non-issue.I was also concerned about the fit of your tank...I normally use Kabukis with the P3 connection, but I imagine for some things I may use a 510 topper now and then. Has that part of it gotten any better? I'm really considering some form of P3 Ti to round out my collection, I just haven't decided which. I'd actually rather have a 2.5 Ti mini, but there isn't one to be found![]()
