JMC, I have a similar device and it works well. I use mine with an HPG chest pack.
I guess I am a little paranoid but when choosing a holster for CCW I prioritize like this:
1. protect the trigger
2. retain the gun
3. place the gun where I can get a full fighting grip before I draw
4. place the gun where I can access it no matter what I am wearing
5. comfort.
I carry AIWB in a Centermass holster when concealed and in a Safariland ALS at work.
I think we have to abandon the idea that we can anticipate how and when the fight will occur.
