the day i bought my XD i went to the store, and asked to see the 4 inch, and the glock 19. the guy behind the counter, as well as the other employees, were all wearing XD's. he said...you know much about these guns? nope. he then takes them apart, and compares them PIECE FOR PIECE, and demonstrates the "beefier and stronger" components of the XD. from the mechanical point of view, i was sold. then he said, shoot them both. i took them back to the range, and went hog wild with 100 rounds each. at the end of those ravishing 12 minutes...the XD won by leaps and bounds.
for me. that is.
:-D
