While you are familiar with the Glock platform, give the XDm Elite10 4.5 a shot. The META trigger is fantastic right from the box. They are accurate and soft shooting. While I like the Glock, the XDm fits my hand better, and if reloads are in the future, the barrel has no problem with lead. The 4.5 or 5.25 give you the option of a solid guide rod so you can change spring rates. It was suggested to me that I put a Wolff 20# recoil spring in it so I don't have to walk two states over to pick up brass. I believe the new Elites have 16 round mags. In fact I looked at a new one that came in a kit with 6 mags for about $659. Check out Powder River Precision for available accessories and upgrades.
