I’ve held both (XD .45ACP, .40S&W and Glock .45GAP, .40S&W) side-by-side. I must say, each time, the XD felt better in my hand. The XD was more comfy and my grip was more consistent with the XD than with the Glocks. Sight alignment was prefect every time. As for accuracy, I have not had a chance to fire either of these two pistols. However, all the reviews I’ve read in the gun mags say the XD is at least as accurate if not more so than the Glock. The fact that the XD was about $100 less than the Glock was just the icing on the cake! Now all I need to do is save enough to put the XD in my holster.
