Depending on day, time of year, weather, 911 could be 45 min, ( One that I can document, on a sunny, June day). We are Covered by Sheriff & MSP ( State police ) but if you are on e place in the county and they are another 45 min is not out of the ordinary. Not the Deputies/ Troops fault, can only be so many places at once. That being said I was driving to a show downstate, I had gone 300+ miles when my Sigma mag started "raining" bullets!! The base plate cracked and came loose and dumped the cartridges. First and only time. But I had two backup mags. So I guess it would be as many as you need- I have not run out. Be Safe,
