well if someone see's the serial number on your gun clearly they will think twice about stealing it.

BETTER - Put a large sticker on the bottom of your gun or anywhere on your gun displaying your name. It will look bad (unless you make it look good ) but would you rather have someone steal your gun?

People will avoid your marker if it has your name on it in a open and obvious area of the gun. You can go to your local walgreens or sports store and get a key bike lock. It takes only seconds to lock your trigger frame to the pole of a table or any stationary object.

NEVER leave your marker unattended
