I have been wanting to get an xd for over a year now, and had gone out and shot them a few times, I really wanted one. I shot other guns and handled other guns first but felt the most comfortable with this one. I was not able to buy any ammo yet, because neither of the sporting goods stores i went to had any. I finally decided i was really going to drop the money on one due to the sound of pistol fire in my neighbor hood two weeks ago. It was that final push to buy something to protect my family.
Any suggestions on what i need to do with this gun or any tips or tricks would be greatly appreciated since this is my first gun.
Best thing to do is run some rounds through it - and find out what brass it likes. I put 50 rounds of WWB through mine with no problems, then picked up some Magtech ammo and promptly had 3 FTF's out of 100. I never had trouble with Magtech in my 9mm Glock, but obviously the XDm .40 didn't care for it. I've got a few hundred rounds of Blazer Brass I'm going to try, and if I have any issues it'll be WWB anytime I'm putting holes in paper. (Hornady 180gr XTP when sitting in my night stand).
