Well, I ran the numbers, and I have to admit I was surprised. The 'ol .45 with hardball did a lot better than I thought it would!

1926 yards (I believe that is the measurement to first impact); quite a bit better than I thought it would be!
More than a mile, and darn close to 2000 yards! But as long as the bad guy stays on the far side of those 20 football fields, he is safe.
However, if you are within a couple more football fields, you are still in danger (?) from a 9mm armed opponent!
(well, whatever "danger" is projected by 22.3 ft/lbs of bullet energy). To save yourself from a bump on the head, all you have to do is
watch for the muzzle flash; from that point, you have about 21 seconds to get under cover or leave the area completely:
Note: While playing around with the program, I detected what I believe is a problem with some of the computations, and I've sent a message to the programmer providing details, in hopes he can explain what is going on. In the meantime, I think most of the info above is pretty close to correct, in an "average-of-averages" way (I ran the numbers 50-60 different ways, and only a few combinations came up with weird results).
