If you have to have a 10mm, I'd stay with the Delta or Glock. Glocks are very depedable, dare I say more so than the Colt. But either will do you well. You may have to have some work on the Colt to make it 100% reliable. Never been a big fan of S&W autos they're too clunky. When it comes down to it, its what feels good to you. Good luck
