Sig just released the P365. 1" wide, 5.8" long, 4.3" tall, it's slightly smaller than a Glock 43 but with a 10 round patented magazine. Cool!
I've played around with this size gun and found it hard to justify when it's to big to pocket carry, and if I belt carry I figured I'd just keep my Glock 26 for 10+ rounds. This could change my mind.
I don't lack for carry pistols so I'm not wanting this in the immediate future, but will keep my eye on.
