Glock 26
Your needs may vary, but that's my vote. I bought a G19 and plan to get a 26 so I can have same platform and function, but the sligtly smaller package of the 26 when needed.
For me, Glock had the reputation, and now my personal experience of being very reliable, low maintenance, and accurate/controlable even in it's compact and subcompact forms.
I've put a few thousand rounds through the 19 in about 6-7 months, shooting IDPA practices with it, and carry it daily now that I have CWP. No issues, no failures, works every time, and is as accurate as I am, or I let it be. Now that my skills are improving the gun is showing it's always been doing it's job.
And, as I say everytime on these types of polls, 33 round magazines.
