First off, sorry for the COD reference, but what else am I supposed to call it. Before you decide you want to go all "rambo" and try to be a bad-donkey, mule, or various other bovine creature, you need to first now the negative and positive sides of dual wielding. Positive: You feel like rambo, though less muscular and slightly more understandable speech. You can put more bbs down range. You can shoot twice as much without reloading,"Based on same-gun use." Negative: Accuracy is literally cut in 1/2 or worse than using one gun. Reloading will be a very huge problem, especially if you're winding hicaps. You're less mobile, as you cannot properly pump your arms to run, and the guns weigh you down, "unless you're using pistols" You don't have a spare hand to grab things, cover, climbing, radio will all become impossibly unless you sling both your weapons. If you fall, you cannot catch yourself. All in all, you've gained more rof and more bbs, and lost mobility, accuracy, and general effectiveness on the field. Now, I have personally dual wielded gas pistols when my primary stopped working, and honestly did very poorly, whether due to a lack of experience with my sidearm or that dual wielding simply doesn't work is debatable. Conclusion, the negatives far outweigh the positives, get one gun, get good with it.
