Seems to work once in awhile. I know of at least one time the stolen firearm was identified within a few days and owner got it back.

I think many times the guns dont even get seen for that 20day period. I get heads up on guns I am intreasted in when they come in. If I want it is marked for me and I return in 20days and pay and pick up.

Does not apply to consignment guns from what I remember.
