Well, as I said: when it comes to reaction fire triggering. That's where the pistol is strong. Especially considering the lack of information about the TUs and Reaction of the enemy. The spread is less of a problem and the reaction triggering is definitely in your favor. Or another way put: You stand in front of the door of a large scout, three men. Run in, take 2-3 shots, run out. you simply can't do that as easily with rifle snap. OK, that's where auto is strong. But only once. After the first salvo, you are usually out of luck, especially if the guys missed and have to get out of there, before it's the aliens turn. Running out is usually out of the question then. With pistols you might even set a fourth and fifth shot, before there is a chance of retaliation by reaction fire. Do that with three men, all of them getting in 2 fields, do the job and get the hell out of there. In my experience, retreating again works not as well with rifles.
