An article I read on the flight to Bogotá...

It's not called a wonder 9 for nothing.

Last week I read another piece about the FBI change back to 9mm. They found the 147 grain bullets gave the penetration they wanted and equaled the effectivness of the 40 S&W. Some female agents also found the 40 to much to handle.

I'm adapting to the trigger, hitting 4" gong two handed at 25 yards with regularity now. Mobil 1 per manual every couple hundred rounds. Not a single glitch yet, getting close to 1k rounds.
