There are a number of potential causes, so unless I see your particular build in my hands, I can not give you a specific diagnosis.

For now mine is a Stock Marui Desert Warrior with only few hundreds of bb's fired
If you're going with custom, see if you can get one hollowed out to fit the Marui grip panel weights. I've never seen mass produced versions of this, except for the panels that come with some Hurricane conversion kits which come with the grip panel weights as well.

tnx I hate the Kimber style and color fo the DW grip
