^Good call vector, read through the whole post to see if I needed to clear that up and got to your post.
Anyway, like a lot of people are saying, I find it a lot better to have it and not need it than to need it and not have it. Last time I played I didn't draw it, but that was one of a handful of games I haven't. I end up going to it quite a bit actually. Occasionally on a CQB field I'll drop my primary and dead sprint all the way to the back of the enemy without them knowing it and take them out with my secondary. My M4 occasionally has some electrical problems, and I'd be very dead on more than a few occasions if I didn't carry it. Overall, I see where the argument for not buying one because it takes up space and is expensive applies. However, you can get a cheap CO2 pistol at Dick's or Wal-mart that costs next to nothing to run, rarely breaks down, etc. and doesn't weigh anything. Heck, it would be worth it to buy a $15 spring pistol to use as a backup. My 2 cents is that you should carry one, because sooner or later, you're going to need it.
