I have a hard time seeing the advantages of a revolver over a small 9mm like a Glock 43 or Sig 365.
There is no advantage. The P365 can be carried with a 10,12 or 15 round magazine. The 9mm is a more potent rd in a small pistol than a +Pb38 Special.
The Glock or the Sig is flatter and in my experience easy to carry
