Jim, I decided not to wait for the Sig P938 to come out and instead bought a P238 "Extreme" model. Picked it up last night and shot 47 rounds through it today. (3 rounds fell out of my bag in my trunk----d'oh.
No issues whatsoever. This gun is dated 5-2-12 so it's quite fresh off the line..lol
Love how easy taking it apart is. As long as the ejector is held down with a finger there's no worry there.
It fits in my pocket beautifully and even comes with a nice little paddle holster.
As far as .380 vs 9mm goes, we shot my 238 against my Colt Gold Cup and friends Springfield TRP at some various garbage we could find the .380 and 9mm penetrated and destroyed the glass bottles and clay targets we had out unlike the .45
