The XD pistols are in fact, single action pistols. However, out of the box at least, I do not think that either them or Glock have a "better" trigger, different, maybe, but not "better".
In response to the original question, I prefer the XD myself for reasons already mentioned. The Glock is just as good though, just depends on which one you prefer.
"Just because the Glock has been around longer than the XD doesn't make it any better. The XD has passed the same reliability tests and even harder tests than the Glock, if that means anything. They both have about the same reliability."
XDKingslayer,
Do you have a link or something that proves this
I would agree with the statement the Glock and the XD have about the same reliability. I currently have 4 XD's and they all run just fine out of the box, just like 4 typical Glocks will.
I don't remember the specific rag or issue, but there's been at least one and I think two 20,000 round torture tests of the XD series. I remember in one case the XD was submerged in a bucket of mud for a couple of days, cleaned up with a garden hose, and then fired 1000 rounds without fail. Good enough for me.
I really don't get where people have this idea the XD is new and unproven. It's just the HS2000 being imported by somebody who knows how to market and sell it. It's been around longer than W has been president and I've never heard of a reliability issue with the platform since its inception.
You could argue it's got a better track record for sheer reliability than .40 S&W caliber pistols from at least two other makers whom I shall not name, and the vast majority of them run like a top of the box, and I can't say that for a certain beloved shooting platform which shall also remain nameless.
