Safariland makes several Duty holsters for the P01.
Go to their website it allows you to search by pistol model.
I also have a KT Mech level 2 retention holster. I know they make a drop leg for it.

Thanks for the suggestion. Yeah, I was already on the Safariland website looking for the P01. I really wanted something more secure than the level 2 retention, which is why I was saying I was really liking the ALS retention and release of the 6350do als holster from Safariland. Didn't know if anyone knew of any other manufacturer making something similar. Would also like to have the canvas cover as an option too. Probably asking for too much...
