I did google it. And you shouldn't have told me to because with these results, you are wrong. Our homicide rate is barely twice what the UK's is (you said it was 4 times as much).
http://en.wikipedia.org/wiki/List_of_countries_by_homicide_rate
U.S.: 5.7/100K
U.K.: 2.03/100K
And...I'm going to go out on a limb here and say that there is probably way more than twice as many gun owners per 100,000 people in the U.S. as there are the U.K., I'd still say we come out on top.
So at best, this proves the homicide per 100K has very little to do with gun ownership.
And given this list, they had to separate England/Wales from Ireland. I wonder why that is; Ireland is part of the UK.

Deaths by firearms per 100K
U.S. 3.72/100K
England: .11/100K
N. Ireland 5.24/100K
So if we combine Ireland and England, the average would be ~2,7/100K
The averaged percentage of households with guns in the UK is: ~6.2%
In the U.S., that number is 39%.
US. 39% gun ownership vice 3.72 firearm deaths/100K
UK. 6.2% gun ownership vice 2.7 firearm deaths/100K
You do the rest of the math, the U.S. comes out on top. The UK has ~2/3rds of the deaths per 100K that we do, yet they have barely 1/7th of our household gun ownership percentage.
There are also plenty of countries with far worse statistics than the U.S. how about you pull the double standards/biased mentality out of your ass, get the fuck off the U.S.'s back and go cite some of those countries?
