I love my G26, it will never get sold, as my girlfriend (now wife) bought it for me. It has been 100% reliable, and shoots much better than I do. It disappears under a T shirt in a comp-tac; Probably the most efficient 10rd 9mm packaging in existence IMHO. A Kahr might be thinner and a J-frame might weigh less (i've owned and carried both), but the G26 is pretty close to the perfect combination of size, firepower and shootability.
That being said, it is on the thick side for tucked IWB in business casual for me (I'm thin framed, so it sticks out too much for my comfort).
