I have this with a light and red dot. The gun is too big to be inside the waistband, and I don't do outside the waistband so far. I have always planned for it to be a home defense gun and currently have a suppressor mounted to it. So....since it has no safety and I like a round in the chamber, I too was trying to figure out holsters.
My solution was to make my own kydex trigger guard holster that works with the light installed. You can also get them commercially (not sure about light being taken into account though): Just first link on google search

Was very cheap and easy to make since I had a square of kydex from previous projects.
