Academy in my area has the Smith & Wesson SD9 2.0 for $299. Basic self protection doesn’t have to be expensive.What does that accomplish ? So you see someone coming and then what ? Call the police and wait who-knows-how-long for them to arrive ? You can get a used (LEO trade-in) Glock 19 for $400 too. If you bought inexpensive Ring cameras, those are $80-100/each, while their better ones are $150-200/each.
