Is there something wrong with the 3-round burst on the Sig? With the M16, if you just fire 1 or 2 bullets(usually 2) when set to burst, the next time you pull the trigger you only fire the remainder of the 3 round burst(2 bullets if you fired 1, 1 bullet if you fired 2). This is because of how the burst mechanism is designed. However, on the Sig, if you fire 1 or 2 bullets and fire again when set on burst mode, you always get a full 3 round burst. Is this a mistake? Or is the burst mechanism designed differently on the Sig?
