You might take a look at a Kimber Solo. Sturdy, reliable, good size. Not a mouse gun, but not too big for most people to conceal.
What about the new Sig 938? Just bought one at a gun show for $600 (great price). Extremely is to carry and very accurate. Love the single action 1911 platform and carrying cocked and locked.
The shield is a great gun.....if you're right handed.
