I would not have an issue with using crimped factory ammunition for self defense as the primer is less likely to be blown out in a high pressure round. I have no idea what they are loading 9mm to, but I have heard things like +P+ level ammunition for the military, because the 9mm is so ineffective.
When I read of the almost proof pressure levels the US Army is loading their environmentally friendly 5.56, they better be crimping the primers because if a primer gets loose in an AR15, it will jam up the weapon. I have not had a primer blow in a Beretta 92, but that pistol has an open top design and you can drop the magazine, rack the slide, and get your fingers in there if need be. An AR15, most NRA service rifle shooters have learned to carry a needle nosed multi tool because the ejection port is so small. I have cleared a number of AR15's, on the firing line, when either a cartridge jams up under the gas tube, or a primer gets loose. First thing to do is put the safety on, drop the magazine, if possible, and separate the upper from the lower.
I had a primer get loose in my match AR15, I had to take the thing off the range and knock out trigger pins, because the primer was way down in the trigger mechanism. I missed 300 rapid fire but was able to join the fun at 600 SF. I never had those sort of issues with a Garand mechanism as junk that drops down into the trigger mechanism is easy to clear, and if a primer got loose in the upper, it falls out.
Anyway, I separate out crimped 9mm and one day, I am going to swage the pockets. I have a ziplock baggy full of the stuff.
