"So be it." Isaint looked down dejected and lowered his gun, switched the safety on and gripped it by the barrel.
"But at least let me grant her a parting gift - something to protect her from the consequences of bad decisions..."He stopped, turning to Spike:
"Shh, Spike, don't go near them, I don't want you to get hurt." Straigthening again he made to fling the gun in his hand towards the troll:
"Catch." [spoiler]
Ok, this is a bit complicated, so bear with me:
First, Isaint's doing a bit of Fast Talk to distract the three:
Con(Fast Talk):
11d6t5 4 [11d6t5=5, 3, 4, 6, 5, 1, 1, 4, 5, 2, 1]
This is followed by a Palming Check to take a gas grenade from his pocket:
Palming:
14d6t5 4 [14d6t5=2, 2, 1, 2, 2, 1, 1, 3, 6, 4, 5, 5, 2, 6]
Thanks to ambidexterity, he is not actually throwing the gun in his hand but the grenade
I'm counting here on the fact that most people just see what they believe happens.
Throwing:
9d6t5 4 [9d6t5=2, 3, 6, 6, 2, 5, 1, 3, 5]
Straight hit into (hopefully) waiting hands. Motion triggered it will explode as soon as it has decelerated.
Why am I doing it that complicated? So they don't use an interrupt action to flee from the gas radius. Also the automatic systems should have problems recognizing it as an attack.
The grenade is filled with DMSO+Narcoject, making it a contact vector toxin of Power 15
A generous GM might increase its power thanks to it exploding in the trolls hands
Afterwards Isaint goes on full defense and prays to all the saints...
