I've been using the BORAII Eagle pocket holster for a week or so.
Works really well in pretty much every pocket I've tried it in, from Duluth cargo pants and their deep pockets to Levi's 505 and their small pockets (of course speed depends on the pocket).
It takes some practice to "hook and rip" the holster off on the pocket corner, but it is intuitive and after some reps it's 100% now. About like learning a waved knife.
