Hmm, I will say this. Guns are not the best way to pierce. Far from it. But they do the job adequately. If you have the time and inclination to hunt out a place that pierces with needles, go for it, and to be honest it won't take that much effort. Especially as you're on the outh coast. My friend at work knows a good place in Bognor, as it happens.
If you just want a lobe piercing that is, admittedly, second best, then getting it done at Claire's ain't gonna kill you.
