It's out of production now, but look for a SIG P250 subcompact. I have one in .380. It's ridiculously easy to rack and it's pocket carryable. With the right ammo, (I use Fiocchi XTP) a .380 can perform close to 9mm levels, and the P250sc can carry 13 rounds. All P250s are DAO. Their triggers are a bit long, but extremely smooth, maybe the smoothest factory DAOs available. They're accurate and relentlessly reliable as well.
All of the above applies to the P250sc in 9mm, except for the racking part. The 9mm version also may be easy to rack, but I've never handled one, so I can't say for certain.
Good Luck!
