Without a doubt there are more aftermarket goodies available for Glock. Nevertheless, I REALLY prefer the XD to the Glock. The fit better, are more feature rich (Loaded chamber indicator, grip safety) and are fun to shoot -and shoot well at that. I carried the 4" XD .40 S&W as my primary CCW for years. I knew it would work when it had to and I played with it on the weekends. Glock seriously needs to update their ergonomics. The guns are reliable but clunky in the hand compared to the XD. Noteable exceptions are the Glock 19 in 9mm, the Glock 23 in .40 S&W and the Glock 38 in 45 GAP. As for the others, Id choose XD any day -especially in a .45 ACP, as the glocks are all too big in the grip area, in my opinion.
