Not BT, but zero issues in three P365’s to date. Current EDC P365X was bought last fall. I treated the mag bodies with Eezox before first use (I have half a dozen or more). Drop of oil on mag release. Hmm about it. (I use Slip 2000). Try for cleaning / lube once a month if I don’t shoot it. Carried the past three months in the RV pretty much all the time.
It’s working so well I decided to go ahead and sell my Gen 5 G19 MOS for another project. I don’t miss the Glock.
