Wall safe quick access solutions

I keep a M&P 2.0 in a wall safe in my bedroom. Due to the depth of the safe it cannot be laid flat and is awkwardly placed. I'm looking for some sort of door mounted solution to keep it secure. The safe is solid steel and the door has no liner, it's painted steel. Any suggestions on good, secure solutions that will not slow me down when I need it? An integrated trigger guard would be ideal. Thanks in advance!
