So much for trying to be funny... Given all the paranoia around here sometimes, I though a non-explicit tip would be appreciated.
But yeah... If people can get hung up on having the proper strength of storage safes, the 'right' kind of gun lock or transport case, having their paperwork in tip-top order and a whole bunch of other legalistic details, it seems to me that it's worth checking to make sure your pinned mags are properly pinned. As well, if you have any manufactured 5-round mags for your battle rifles, it might be a good idea to see that a sixth round can't be slipped in. However if you think this is a silly concern, please don't bother taking the 5 minutes to check...I'm sure no officious club or range officer or anti-gun cop ever will...
