OBTW, the "critical defense" ammo is very good defense ammo. It is designed to penetrate approximately 12 inches and mushroom very well. For .380 ammunition it costs about $1.25 a round. Not cheap, but if it penetrates in the body like it is supposed to, then it will be very effective. The green/red tip keeps the hollow point from being clogged up from your attacker's clothing when it penetrates; which has been a problem with hollow point ammo.
Hornady even makes a .22 Magnum CD round. It launches at over 1000 fps out of a 2” barrel and gets 9-11” of penetration in gel with an almost 100% weight retention. It’s perfect for a S&W 351PD backup.
