To my dismay, I've reached the age where toting around a BHP or other big-*** metal frame pistol is not an option, and in fact, many options have been receding as I get older. It isn't from lack of proper leather gear, either.
I was very happy to carry a Beretta or SiG .380 and still do, but the SiG P365 has been a game changer for me. I mean, look at this list of guns (allmost all of which are long gone) at the comparative weights here.
NOTE: these are loaded weights, usually with the the heaviest bullet I can find in that caliber. The list is a powerful argument that the P365 is an ideal combination of weight, caliber, capacity and reliability. And I'm not really a SiG guy - I far prefer Walthers. I find the P365 a rather soulless although perfectly reliable little product.
