I shot over 10,000 rounds through my XD9. The list includes Winchester White Box, Winchester Ranger, CCI Blazer Brass, CCI Blazer Aluminum, Speer Gold Dot and Federal Hydrashok. I had less than 10 cases of feed or ejection issues when it was under 200 rounds. After that, it was flawless. There's a thread on here about my 10,000 round XD9.
