Silly question

[mischief]

I admit my ignorance in this, why are Sig Sauer handguns called a "Six hour".
I bought a Mosquito on Saturday but have to wait for Sportmens to finish moving to pick it up and when I called the CFO of Alberta the Lady that was helping me kept referring to it as that and I have really bad curiosity. Thanks for the help.

Simple mis-pronunciation that all!

I wondered if that was it but when I googled it there was a reference to a joke. Thanks for the info.
