Hi,
I have a bit of a problem with the fire selector. Per the RAW, "a weapon with a fire selector can have up to three different clips added. At the start of the shooter's Turn, he can use his fire selector to choose which clip he wishes to draw ammo from that round."
Two problems:
1) It's not stated what type of action a character uses to choose a clip. Free action, Reaction, half action, what? As written I'd be inclined to interpret it as a free action.
2) Doesn't a fire selector basically make rapid reload and in fact reloading in general as good as obsolete for SP/Bolter pistols/basics? With the ability to have 4 clips total (or 3, depending on how you read it), you will rarely need to reload at all?
The solution our group chose is ok, but completely illogical. At the start of each round, as a free action, you can choose which ammo you use that round as long as your total ammo supply indicates you have enough of that ammo. Each clip still has the same number of bullets/shells, but you can freely choose each round what ammo type you want.
