I am getting an Xdm on my 21st B-Day (4 days) and was wondering if their are any accessories I may want to get? I already ordered got a holster for CC (crossbreed quikclip) but wonder if their is anything else? I know it comes with a lot but wonder if their are any mods that may make the XDm even better. Thanks. PS. I am new here, from SW Ohio.
