Hey there fellas, just bought a XD(M) 9mm in DO with stainless slide and TRU GLO sights. This thing is a work of art. Anyhow, when a full mag is place in the gun...there is a rattling noise. Like a babys toy. But if I put one in the chamber it stops. Is it to new? Needs to be shot? I don't like to carry lock and loaded. I also can't carry a weapon that rattles fairly loud. If I can hear it, others will know doubt hear it too. So much for concealmeant. Any answers out there???
