Black Arch Holsters makes a single-clip Protos-M for the P-01. This is the only hybrid holster I own for my P-07. I consider it superior to any "regular" hybrid holster design because the Kydex shell wraps around the trigger guard and retains the gun like a full Kydex holster would.
I also used to have one of their dual-clip models, but like you I find them inconvenient to put on and take off, so I sold it a while back. If I was going to have a dual-clip hybrid, that's the one it would be.
For a different pistol that Black Arch doesn't make a holster for, I have a single-clip hybrid from Hidden Hybrid. The retention isn't as good as a Black Arch holster, but it isn't as bad as some others I've tried. They use a thick piece of leather and a fairly tight Kydex fit on the outer part of the trigger guard to achieve that. They also offer a claw option on their single-clip holsters, although mine doesn't have one.
