Wouldn't this work better for getting what weapon the player has? http://www.zeroy.com/script/player/getcurrentweapon.htm

so is my theory correct? i was going to test it like a week and a half ago but i had to reinstall mod tools again  

Yah don't know if it is a trigger_shoot but I don't remember haven't messed with mod tools for a while.

Script()
{
	Trig = GetEntArray( "ENT", "targetname" );
	for( i = 0; i < Trig.size; i++ )
		Trig[i] thread Shooot( "WEAPON_NAME" );
}

Shooot( PassWeap )
{
	for(;;)
	{
		self waittil( "trigger" );
                Weap = self GetCurrentWeapon();
		if( Weap == PassWeap )
			break;
		else
			continue;
	}
	// What you want done here
}

//thread shootme();
shootme(){
	triggers = GetEntArray( "ENT", "targetname" );
	for( i = 0; i < triggers.size; i++ ){
		triggers[i] thread shotit("zombie_colt");
	}
}
shotit(weapon){
	currentgun = "";
	while(!(currentgun==weapon)){
		self waittill("trigger", player);
		currentgun = player GetCurrentWeapon();
	}
	//Do what you want here
}

There is a typo on the waittill("trigger") and it would be GetWeaponsListPrimaries, and I'm not sure if you can GetWeaponListPrimaries from the trigger. I like that you thought to getentarray instead of just getting one. May I suggest the following modifications:

//thread shootme();
shootme(){
	triggers = GetEntArray( "ENT", "targetname" );
	for( i = 0; i < triggers.size; i++ ){
		triggers[i] thread shotit("zombie_colt");
	}
}
shotit(weapon){
	currentgun = "";
	while(!(currentgun==weapon)){
		self waittill("trigger", player);
		currentgun = player GetCurrentWeapon();
	}
	//Do what you want here
}
