Concealable holster with auto retention mechanism

[MAKster]

I'm looking for an OWB polymer holster with a locking mechanism for my Glock 19. My first choice is one of the Safariland models with ALS (#6378 or 7378). The problem is that these locking holsters hang much lower on the belt than a typical pancake style holster. The bottom of the holster is exposed even when wearing a jacket. It appears from photos that paddle versions ride a little higher but I'd prefer belt loops. Does anyone know of a holster with an auto lock mechanism that is actually concealable under an untucked shirt or light jacket? Thanks

Using my detective skills, can I guess you are law enforcement of some kind. That'd be the only reason for a retention device on a concealment holster.
