After owning several Glocks, I eventually decided that I needed to try an XD to see how they compared.
So I bought an XD45 Tactical.
After owning and shooting it for about six months I had to admit that it just wasn't for me.
There was just no denying it, I shoot Glocks better.
I don't know if it was the higher bore axis of the XD, or the trigger of the XD, or the grip angle, but for whatever reason I was much more accurate with my Glocks than I was with the XD.
Three things that I really disliked about the XD:
1) The slide cannot be racked unless the grip safety is firmly pressed.
I cannot count the times I had to slightly readjust my grip in order to deactivate the safety and rack the slide.
2) I didn't like the trigger-pull all that much because it was long and creepy.
3) It's much more difficult to detail strip than a Glock.
What I did like about the XD:
1)It never failed to fire.
Of course none of my Glocks have ever failed to fire either.
2) I like the take-down method for field stripping the XD.
It's a good handgun.
Just not as good as a Glock IMO.
