High capacity magazine question

[Dave Block]

Where would a 1914 DWM artillery luger with plank stock c/w leather holster and 32 round snail-drum magazine fit? The pistol itself is registered (with 8 round mag) but the rest wasn't brought to the authorities attention at the time. I'm not admitting to anything personally here but will gladly show them where to dig if they come banging at the door (I need a new sump-pump hole in the basement).

Cheers, Dave
