Have both glocks and XD's & XDM. Love them, biggest difference by feel and external looks is that the Springfierlds have a few bells and bits the Glocks don't. IE a grip safety, cocked indicator, and loaded chamber indicator. All nice but not must haves for many people. Both are very good pistols, just find one you really like the looks and feel of and go for it. You can get one of the others next time. After all one is never enough.
