NO. They are not compatible. I have both, the Warrior holster is still too narrow for the Mk23 even when adjusted to max size. I use a Viper adjustable holster which is a cheap option and works.
I bought the Warrior holster before deciding on which pistol, changed my mind on what to get, and was disappointed that it was too small. It is a nice holster which I hope will fit the HK45 when I get one.
