It appears to me that most other guns like XD just to pick an example are "top heavy" looking. Meaning the slide and frame are higher up above your grip as compared to a Glock. Seems to me that this would make the Glock a much more stable platform to shoot. The XDs to me just look so top heavy and seem like they would be more difficult to shoot. Don't think I have seen to much discussion on this aspect when comparing different guns. Is there any significance to this difference?
