There are plenty of people out there that like the Bersa and the XD both and with good reason; both are fine weapons. As with any, you want to make sure they're well broken in and well maintained for proper reliability. You can go Glock as suggested, or S&W, or Sig, or Kimber; but since that's not what you asked I'll not go there. A well broken in, well maintained, and frequently verified Bersa or XD will be as effective of a tool as any of the others mentioned that have been provided equal care.
