I recently picked up a Glock 42 and have enjoyed carrying it as a BUG on duty, and throwing it in my pocket. I was hesitant on going to the .380 also, but it was the next smallest option for me as a BUG, aside from my 26. I haven't had any issues with mine, I've just been trying to find a pocket holster for it.
I have the original XD40 and it's an outstanding gun. The subcompact series are great too, but they're no slimmer than my Glock 27.
I've given up on little diddlybop snubby guns and have gone back to my 1st love. It ain't sexy, it ain't got lights and lasers all over it, but it's got a match grade barrel and I'm hitting paper plates the size of a man's face at 25 yards. I stick it in my belt, it doesn't print and when I pull it out you're lookin down the big tube. Springfield Armory mil-spec 1911-A1. It chose me many years ago. It completes me. I am now complete.
