In my opinion there are a few guns that the rest of the field is trying to be "just as good as". And many of them are, but they lack the long history of the first and unless there is some persuasive reason to choose a new comer, then I would go with the old standard.
In 9mm my choices for a "standard" are these: Glock 26, Glock 19, Glock 17; Beretta 92, Browning Hi-power (or their current production equivalent).
For .45, Colt, Sig, Dan Wesson, Smith & Wesson and Kimber (full sized weapons and commander sized weapons only).
Note: On the 1911 most of the full sized weapons (of all manufacturers) and most of the commander sized weapons are reliable. The compact and subcompact are far less likely to be reliable. If you want a small .45 I'd sooner go with a Glock 30 or a Glock 36.
