A bit of a tangent, but this discussion does bring up an interesting point regarding the Pistol Grip attachment.
Frankly, is the shooter required to use the attachment at all times?
As part of keying up all the Dangerous Covenants crunch for OggDude, I've been reading (and re-reading) quite a fair chunk of the material, and with Pistol Grip, i could see a GM ruling either way.
Personally, I'd say it's an option, and that if the shooter wants to use Ranged (Heavy) as would be normal for a blaster rifle that has the Pistol Grip attachment, then the shooter can go ahead and use Ranged (Heavy) as their attack skill and pretty much disregard the rules of the Pistol Grip as they're using the rifle properly.
In the movies, we see the stormtroopers constantly using their E-11 blaster rifles* with two hands, one on the grip and another under the barrel to improve their aim. And yes, I'm one of those that thinks the main reason we say the stormtroopers being so inaccurate during the escape sequence in ANH was they were under orders to let them escape. It also goes to show the level of devotion and dedication they have to the New Order that these men were willing to put themselves at great risk (with several of them dying in the process) just to further Vader's plan of action (let them escape and track them via homing device).
*to my dying day I will insist those bloody things should have been termed carbines in the RPG rather than being rifles
