No offense guys, but I'm tired of hearing people go on and on about how big and bad a desert eagle is. First of all, it's heavy as hell, and the heavier a gun is the less it kicks. Second, the 50 Action Express (the one everyone thinks is so amazing) is pretty much a glorified .45. It can't go through a city block full of houses! Now, one of my financial advisors has a gold plated desert eagle chambered in .44 mag (not bad) and it doesn't kick that much, though it is considerably more than if chambered in .50.
As for shooting two handguns at once, it's possible. Not neccessary, but possible. If your shooting two handguns, the objective is probably different and you are just throwing out lead, or as I like to say, "sprayin' and prayin'"! Seeing as how it is harder to be accurate with 1 pistol than a rifle, you do sacrifice accuracy even more if you double up. But, I've shot two pistols at once in real life (my H&K USP .45 and my friends Beretta 92) and it wasn't entirely fake, although it was much more difficult.
Keep up the interest, everybody!
