It has been brought to my attention that I have overlooked a couple of rules, especially when it comes to combat. I was under the mistaken impression that SS weapons were the only type of pistols that could not use two simple actions to fire twice in the same phase. The actual rules are that NO simple-action attack can be combined with another simple action attack. A "multiple targets" action can be used to split your dice pool between two rolls, but the remaining simple action must be spent doing something other than attacking.
Another rule I missed is that single-shot weapons (like Saint's revolver) are immune to recoil. All other weapons keep accumulating recoil until the user spends an entire action phase not-shooting. So to recap, here are the strengths and weaknesses of the fire modes:
Single Shot (SS) - No recoil
Semi-auto (SA) - can use a complex action to fire a burst (3 bullets - giving the enemy a penalty to defense)
Burst Fire (BF) - fires a 3 bullet burst using a simple action (instead of a complex action, like SA do)
Long Burst (LB) - a burst-fire weapon can use a complex action to fire 6 bullets, giving an even greater penalty to defense
Full Auto (FA) - complex action, 10 bullets, extreme penalty to defense
I'll begin enforcing the above rules in the next chapter. Please accept my apologies! This edition of Shadowrun is new to me.
