animation not playing all the way through - swep

[ewmiter]

hello i have a script that plays an animation on primary fire but it dosn't go all the way through the animation but sometimes it dose

function SWEP:PrimaryAttack()
	if !IsFirstTimePredicted() then return end
	local trace = self.Owner:GetEyeTrace()
		if CLIENT then surface.PlaySound("tools/hammer_hit2.wav") end
		self:SendWeaponAnim(ACT_VM_HITCENTER)
		local effectdata = EffectData()
		effectdata:SetEntity(trace.Entity)
		effectdata:SetOrigin( trace.HitPos )
		effectdata:SetNormal( trace.HitNormal )
		effectdata:SetMagnitude( 1 )
		effectdata:SetScale( 1 )
		effectdata:SetRadius( 1 )
		util.Effect( "Sparks", effectdata )
	self.Weapon:SetNextPrimaryFire( CurTime() + self.Primary.Delay )
	self.Weapon:SetNextSecondaryFire( CurTime() + self.Primary.Delay )
end

[URL="https://youtu.be/x6paKw6QDhE"]here[/URL] is a vid of the results
ACT_VM_HITCENTER is the swing animation
help will be thanked

Only use IsFirstTimePredicted for unpredicted functions.

function SWEP:PrimaryAttack()
	if IsFirstTimePredicted() then
		local trace = self:GetOwner():GetEyeTrace()
		local effectdata = EffectData()
			effectdata:SetEntity( trace.Entity )
			effectdata:SetOrigin( trace.HitPos )
			effectdata:SetNormal( trace.HitNormal )
			effectdata:SetMagnitude( 1 )
			effectdata:SetScale( 1 )
			effectdata:SetRadius( 1 )
		util.Effect( "Sparks", effectdata )
		
		if CLIENT then
			surface.PlaySound( "tools/hammer_hit2.wav" )
		end
	end
	
	local delay = CurTime() + self.Primary.Delay
	self:SetNextPrimaryFire( delay )
	self:SetNextSecondaryFire( delay )
	self:SendWeaponAnim( ACT_VM_HITCENTER )
end
