First, you're dodging the bottom line.  The term, "For secruity reasons" is not a supportable statement.  It implies that they knew what Glock was THINKING when they brought it out.  I don't either, but my conjecture is just as good as Janes'.  Now, that makes the statement unsupportable and calls the source into question.

Second, are you SERIOUSLY calling one of five sources provided into question when it agreed with the other four?  I believe that this is a case for you to bring up with the WP community board, not here.  If the other four are reliable, and this single source agrees with them, it's reliable also, eh?
