The Sneaky Pete Holster finally got here. It was out of stock for the p365, but Im telling you, it is worth waiting for.
The only down side is the physical size, which is roughly the same as a large cell phone case, but with the vast selection of cell cases around, it doesnt draw any attention at all. What it does do is 100% conceals the gun, has pretty strong magnets holding it closed (but not so strong as to prevent a reasonable draw), and the model I have uses belt clips which are very reliable.
Ive worn it the entire time Ive had it now, and it is so comfortable I really forgot I had it on. This is now my new favorite holster, well made, rugged, and the gun fits in it perfectly.
If you are looking for a quick draw holster you may want to keep looking, but for total concealment in summer wear this one is the cats n***!
