I carry mine with a cold chamber, so the safety doesn't matter a bit to me. The Fireball is a bit louder than the Hornet, but not enough to matter much, it all depends on how you load it and with what charge of what powder, I use Reloader 7, and I'd consider it "in between" the Hornet and the .223. I've tried Lil Gun in it, and it cracked like a stick of dynamite, didn't much care for that aspect of Lil Gun at all.
The bad thing about the Fireball is the price of brass, Remington brass is crap (needs annealed out of the bag) and Nosler(Norma) is expensive. All told, I'd buy the Nosler brass and forgo the Remington crap brass altogether. That's the only headache I have with the Fireball, it's a great little cartridge.
