I recently purchased an XDM9, it was new from the LGS. I got to looking thru the papers and the gun and it is a 2009 model year. It came with two magazines and I purchased three thru Springfield's webstore. I loaded the new magazines to full capacity and I can not easily fully insert the mags. When I get the mags fully seated I am unable to depress the magazine release button. So I now have a magazine stuck in my new gun. I work the slide and take two rounds out and it operates correctly. I load my mags with 17rds instead of the full 19 and gun and mags mate perfectly. What could be causing a fully loaded mag to be hard to insert? Why can I not remove the fully loaded mag?
