I would shoot the heck out of it, (and have), for practice ammo. Howver, I cannot imagine staking my life, or that of my family on it. Blast up the cheap stuff, and stoke up your mags with some quality, expanding ammo from a reputable maker for defense. Buy at least two boxes, and make sure that your pistol functions reliablly (not difficult with a Glock). Then run as many defensive rounds through it as you can afford. load up, and you are alright.
