My Next Pocket Pistol For EDC

Now that all wedding stuff is done with for me I can finally focus my money on fun stuff again... My next venture is what pocket pistol to get! I've got narrowed down to the Ruger LCP (.380), S&W M&P Shield (9mm) or the Keltec P11 (9mm). I'm liking the 2 9mm pistol choices as I don't really want to add another caliber to my family of firearms but the size on the LCP is pretty darn nice. Ideas?
