There's 84 total grenade launchers in the data set, if you are curious. Florida took twice as many as CA (36 to 18) and the rest of the states with them are under 10. Why Florida needs so many is another question...
Also interestingly, Montgomery got all 9 of AL's grenade launchers, more than Sacramento or LA took.
edit: actually, this data is wrong because I only used the first page, didn't even see the other 3....
