enough choices to make a 'list'
Glock M17
CZ75
S&W M&P
Springfield Armory XD (and this one comes with serviceable, albeit NOT fancy, gear)
Ruger choices
Hmmm...I'm sitting here, looking at my list, knowing what I know now.
I'd have to pick either the Glock first (even though I won one once I wouldn't, because they don't fit my hand, but it may fit yours) due to its overall goodness-as-gun, and the availability of EVERYTHING for it, or the S&W M&P or SA XD.
Whichever fit my hands best.
That said, I own three CZ clones.....
