nice but the velocity thing is kinda hacky. i took a look at the pistol code and got this:

VPROF_BUDGET( "FX_MuzzleEffect", VPROF_BUDGETGROUP_PARTICLE_RENDERING );
	
	CSmartPtr<CSimpleEmitter> pSimple = CSimpleEmitter::Create( "MuzzleFlash" );
	pSimple->SetDrawBeforeViewModel( true );
	
	pSimple->GetBinding().SetBBox( origin - Vector( 4, 4, 4 ), origin + Vector( 4, 4, 4 ) );

	Vector forward;
	AngleVectors( angles, &forward, NULL, NULL );

	SimpleParticle *pParticle;
	Vector			offset;

	float flScale = random->RandomFloat( scale-0.25f, scale+0.25f );

	if ( flScale < 0.5f )
	{
		flScale = 0.5f;
	}
	else if ( flScale > 8.0f )
	{
		flScale = 8.0f;
	}

	//
	// Flash
	//
	int i;
	for ( i = 1; i < 9; i++ )
	{
		 offset = origin + (forward * (i*4.0f*flScale));

		pParticle = (SimpleParticle *) pSimple->AddParticle( sizeof( SimpleParticle ), pSimple->GetPMaterial( VarArgs( "effects/muzzleflash%d", random->RandomInt(1,4) ) ), offset );
			
		if ( pParticle == NULL )
			return;

		pParticle->m_flLifetime		= 0.0f;
		pParticle->m_flDieTime		= 0.01f;

		pParticle->m_vecVelocity.Init();

		pParticle->m_uchColor[0]	= 255;
		pParticle->m_uchColor[1]	= 255;
		pParticle->m_uchColor[2]	= 200+random->RandomInt(0,55);

		pParticle->m_uchStartAlpha	= 255;
		pParticle->m_uchEndAlpha	= 255;

		pParticle->m_uchStartSize	= ( (random->RandomFloat( 6.0f, 8.0f ) * (8-(i))/6) * flScale );
		pParticle->m_uchEndSize		= pParticle->m_uchStartSize;
		pParticle->m_flRoll			= random->RandomInt( 0, 360 );
		pParticle->m_flRollDelta	= 0.0f;
	}
