lead bullets in glocks are a bad idea. the flat nosed lbt type slugs also may not feed in an auto. also bad. real solution is to forget the handgun and use an appropriate long gun. 12 ga with slugs or carbine 45-70. even though both of those will have recoil, she won't notice it if it needs to be used. but,practice,practice,practice. this sort of sound like an accident waiting to happen though.
