one could argue the same about why the Springfield XD, Ruger SR 9 and Beretta PX4 are $100 cheaper than the glock?
no one will ever know.
I personally much prefer the XDM to any glock model. also the XDM9 compact is smaller in overall dimensions than the glock 19. the XDM is more comparable to the glock 26 with almost identical OAD. if you are looking for a concealed carry gun the XDM is the way to go.
