Dirtypipes...
are you set on double action? Or would you consider single action IWB for concealment? I can hide my Colt Mustang Plus II (380) very easily in a IWB carry. My best friend swears by his SIG P238. I have carried the Mustang in pocket inside a Nemesis type holster with no printing either. Most people don't like cocked and locked in their pocket though. I understand their angst.
Of the DAO's you mentioned, my best friend owns a Kahr 9. Small, difficult to shoot, the mags fell out of the gun while he was firing it!! If I remember, the extractor also broke. In short... he hates it. Its now his first 'Safe Queen."
I've fired another friend's Ruger LCP. Would hurt my hand if I shot 100 rounds through it, but handled well for a short range "get off me" firearm.
All this said, If you can... stay with an IWB holster and consider a slightly larger weapon. Grouse's suggestion of the Kimber Solo in DAO (2.7" barrel) or the Springer EMP (3") in SA might be more gun, more reliable, and more fun.
My daily carry is a DW CCO in a IWB holster under a sweater vest. In summer, I wear a tuckable holster, or shirts outside the pants. Haven't been printed yet.
Just my 2 cents,
Da
