"London has far more gun crime than much of the US does"

Can we get a figure to back that up please? The MET places gun crime figures in greater London at 1570 (http://www.met.police.uk/crimefigures/) with a population of approx 8 million. Which American populations would you compare this to and what are their figures?

I've spent a significant amount of time in London and have never once run into any firearms incidents. It would be interesting to me to see the data behind this.

There is no shortage of small communities across America that have not had a gun crime in decades. Zero stays zero, even when you make it per-capita.

Whether or not this is a fair comparison is another matter.

Fair call. To clear that up I would count urbanised centres of a similar population size and density would be a reasonable basis of comparison. I imagine England would have a large number of small communities with zero gun crime as well.
