Really? I find it the other way around. without a silencer, I tend to hold down the trigger, on say the famas, and it takes a whole clip until the guy dies. with a silencer I can take my time if they don't know I'm there, and if I burst fire (like how the famas was in mw2), then I almost never take more than 4-5 bullets. Although... in close-quarters combat, I find that hit detection is suddenly 100x worse, and silenced weapons don't work
