Glad I got a M&P 340 I guess a couple of extra ounces with the SS cylinder makes a heck of a difference apparently. Have you tried any Speer Gold Dot .357 135 gr for short barrel? Give them a shot, you might like them.
I think the benefit of what you have is lightweight carry, but I think my favorite load would be standard pressure 20C BB in the Sc/Ti machines.
I guess the HM didn't fit your hand so you "customized" them.
