my XDM 10 is easier to hold and shoot than my Glock 20, both are great guns, but this XDM fits me better and I'm much more accurate with it, hope this helps...Great review of the XDM. I'm curious, did you have any issues with the grip size? A friend of mine had a Glock 20, and with the double stack mag, it was too much for me to hang on to comfortably without having to re-adjust my grip after discharge. Do you have any experience with the Glock 20, and if so, how does the grip compare? Thanks for your time on this.
