I also keep an Excel spreadsheet of my weapons serial no , cal , receipt number and dates on my desktop and laptop along with a copy uploaded to my website . IF you don't get a car safe try using on fo those cable locks , I just run it through the mag well up through the open slide and around the seat adjustment rail (I usually have to string 2 of them together ) DON'T run it throught the trigger guard becuse the BG with just break it off .
