I just recently shot my new XDm 5.25 / 9mm and found it to be a superb polymer version in this calibre. Haven't had the opportunity to shoot the .45 in the 5.25 series, but I do have one in the .45 XDm and love it. Next to my 1911's in Colt and Kimber, my XDm .45 is my "go to" pistol if I want to shoot lots of rounds in a reliable and extremely well built polymer pistol. Yeah, the slide hits hard, something you have to get use to if you are use to shooting the much heavier and beloved all steel versions. Sorry you were disappointed in it.
