Given the four models you site, how much experience do you have with weapons of any type? Any what types are they?
Your experience will HIGHLY influence the choice only YOU must make. The Glock 26 is a nice weapon, as is the USP Compact, although there are some differences in the controls, the M&P is okay, but I'm not sure whether you're referring to the DAO Compact version of the FN when you say "Browning model." There really is no "compact" Browning HP...and I assume it is to that you're referring.
You can lead us, and we can give advice, but you will have to make the decision.
What advice we give...depends on you.
