Hi folks! Just bought a new XD-40 sub compact and I'm not sure if I have a problem. When I load the magazine and put it in the gun with the slide closed, the magazine doesn't want to latch in place unless I hit the bottom of it. Also, when I try to release the full mag, the release button is VERY stiff. So stiff that it's impossible to release the mag with my shooting hand thumb. If I load the full mag with the slide open, it goes in easily and releases easy. Same with loading and releasing an EMPTY mag with the slide closed...no problems. Is this a problem or could it just be that the gun is new and hasn't had any break-in???
