You really think that an organized military and police force can be stopped by citizens (including grandma) with their .38 S&W?
Back during WWII, the US OSS (Office of Strategic Services) had this really cool idea, which was held as classified until the end of the war: they were going to drop hundreds of thousands of these little, very cheaply made .45 caliber single shot pistols (with a handful of shells and an instruction manual), from airplanes into occupied France. The idea is, in part, that partisans would use them to stick up / kill German troops and borrow better weapons.
Problem is, by the time this idea was about to be implemented, the French Resistance already had accomplished this, using revolvers and other small arms which were hidden from confiscation, and they had worked up to stealing heavy machine guns, Panzerfausts and other types of heavy duty stuff. There were a number of drive-by style machine gun assassinations against German officers, and they were becoming such a thorn to the Germans, that French hostages (women and children of course) were rounded up and executed to dissuade the resistance--several times during the war.
Airdropping these pistols wouldn't accomplish much at that time they were completed, so they didn't fly. The point is this: you shouldn't underestimate the difference a simple, low power weapon can make, at the right place and time.
