Although I have since gone to a Glock 17 with a light and an optic (I'm big enough that it is concealable in nearly every circumstance), I think the answer to the question as posed was, is and for the foreseeable future will be the Glock 19.
I wrote extensively about why in this piece from almost exactly fifteen years ago.
The truth is that I don’t love guns. I appreciate guns. I am pleased to discuss guns. I enjoy competing and training with guns. Guns have a ...

Some excerpts:
What makes a firearm beautiful to me, what I admire above all other qualities, is reliability – the weapon's ability to function as it is supposed to function tens of thousands of times in a row without a single failure. Certainly a firearm ought to fire a caliber useful to the task; and of course I need to be able to shoot that firearm accurately enough to put rounds into a useful part of the target. But if a gun will only do that 999 times out of thousand, it’s of no use to me. That weapon might belong in some collection, but it doesn’t belong in my holster.
Thus, my relationship to firearms is a utilitarian one. Their possession serves an essential, but narrow purpose. They exist to accomplish a task. They are the necessary tool for a job I hope not to have to do. One might as well speak of a pretty life insurance policy. For me, collecting guns would make the same sense as collecting hammers, or circular saws, or snow tires. Like some hoplophilic disciple of
Louis Henry Sullivan, I demand that, and am pleased when, a gun’s form follows its function to the essential exclusion of all other aesthetics.
The function at issue is defense of life
in gravest extreme. If such defense of your life and the lives of others is a God-given natural right --
and it is -- then your choice of the tools you employ in that exercise is necessarily a matter of great moment. To be clear, it's not even slightly as important as having the right mindset or sufficient training. But tools do matter, and among the tools I choose is the ugly black pistol pictured above, a Glock 19.

Robert’s Rule states that “Simplicity is Murphy’s only natural enemy.” At the core of what makes this pistol reliable (which is to say beautiful) is that it is about as simple as a pistol can be. It takes perhaps two minutes to
learn how to “field strip” the Glock 19 – that is, to disassemble it into its major components for cleaning and maintenance. Each time after that initial tutorial, field stripping and reassembly take about 12 seconds each. No tool is necessary to accomplish this. Beyond that, the pistol can be completely disassembled into its only 35 parts with a simple punch in perhaps a minute.That's kind of lovable, too.
Another of Robert’s Rules holds that “Only a fool tries to say better what has already been said perfectly.” Better, like a good reporter, to quote with full attribution:
"I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend" J.R.R. Tolkien, via Faramir, in The Two Towers.
