how many rounds does that hold?
I agree with this 100%, particularly because I carry my BUG on my ankle. I can reload my primary a LOT faster than getting to the BUG (at least from most positions).I have never bought the argument that the fastest reload is another gun. I don't think it is natural for anyone (unless you have specifically trained extensively doing so) to throw away/put down/reholster/drop their firearm they are using to fight off a threat and reach for a different gun; one that is presumably in a harder to get to area (deep concealment) and continue on. Im sure most of us have worked on reloads, either in competition or just practicing at the range and it would be much more natural/convenient and faster for us to keep our primary gun in the strong hand and simply retrieve a magazine with the other. The gun stays relatively close to on target and you're brain isn't trying to process dropping one gun and going to another. Just my .
Now if you don't carry a reload for you're primary...
