Mom should get a Saiga 12 with a few 12 round mags for in the home use.
Sadly, illegal in the People Republic of MA.
Weapons are not for self-defense, but for peasant, er, I mean pheasant, hunting.
Witness the guy who was attacked by a bear in his back yard being prosecuted by People’s Republic.
A Saiga12 is too heavy for most ladies... After trying several things including the Saiga12 the wife settled on a Mossy .410 pump with Winchester’s self defense loads and a Sig P232SS .380. I would rather see a lessor hit than a flinch and miss with a heavier round.
