I know this is an old thread, but I had a similar problem when carrying on a motorcycle. When I had all my protective gear on, it was hard to reach the gun. When I wasn't ATGATT the gun would print or poke into my side. I didn't buy this pouch with the idea of putting a gun in it, but it did work really well when I tried it.
It's anchored on the strap so it doesn't slide at all. Not as quick as some options but also doesn't scream "GUN!"
