When I wear a tucked shirt and no coat, I have been using a PPK in a Galco USA http://www.usgalco.com/HolsterPG3.asp?ProductID=1748&GunID=168 . It isn't the fastest by any means, but it is always there (as is a spare mag in my left front pocket). A G19 goes in my computer bag where it is accessible though an unzipped flap. When I have a cover garment, the G19 goes in the waist and the PPK to the computer bag.

They stay at the office or my car, but I don't go to court too much anymore. Guns are not my fear. I worry more that I will forget a spare magazine or knife somewhere for Mr. Marshall or Officer Friendly Helper to discover.
I pat myself down before I go into the courthouse. It's the only way to make sure I don't miss a knife or two.
SmartCarry. Get it for the J-Frame and carry that, a KelTec p3at, p32, or a compact Glock with a reload too.
It works well. Might be too ultra deep but the draw is not that bad.
