I'm thinking of getting rid of my M&P40C for a lighter carry gun. Anyone think I should/should not? (Thinking Glock 43, M&P Shield or Glock 26 off the top of my head. Hate stock Glock sights, though) I'd prefer to stay .40 S&W so I don't have to stock another caliber, but open to 9mm.

Started carrying my XD40SC today to see how much better, if at all, it feels for me vs the M&P. I carry everything IWB via Crossbreed holsters. Maybe the holster is my issue?
