Update: So I bought a bunch of mags around xmas time for my Glock and after setting the alarm off at Borders today and finally had had enough and tore through everything. I have had a sticker on one of the Mags that said the price on it. I just kept it on as I number my mags and it was a good spot to write on. The thing is like a metal sticker. So I am sure I have found the RIMFPK-49'er thing. This little son of a bitch has caused me more grief than I can even describe. Man almost every store I have walked into since December I have set off the alarms. Thank god this over.
I wonder about all the stores alarms I didnt set off, does this mean I can steal from them and not get caught?
