We were directed back to the register where they once again scanned the box to deactivate the electronic tag. When we reached the door again, the alarm sounds. Back to the register, repeat the process. Head through the door, the alarm goes off. They just let us go on that time because the security person had seen the receipt and had gone back to the register with us.
I began to wonder about it, much like the OP of this thread. I was carrying my Kimber, equipped with Crimson Trace laser grips. I left the Kimber in the truck with my wife and walked back through the door.... nothing. Went back to the truck, re-holstered the Kimber and re-entered the store. Made a u-turn for the exit and the alarm went off again. The same security dude just said go on.
Wondering about the grips, I flipped the power switch on them to the off position and went back through the store with the holstered Kimber. Nothing... no alarm.
I understand what some of y'all are saying about the tags being the culprit, and I don't know enough about those types of systems to argue. All I know is that with the CT grips powered, the alarm went off.... several times. Without the gun on my person, or without the grips being powered.... no alarm.
I was back in Wally World today. Turned the power switch off on the laser grips before I went in.... no alarm.
I am writing a letter to Crimson Trace and I hope to hear back from them on this. Might be nothing, might be interesting.
