Not to get onto the topic of a 22 for SD, but my wife has been carrying for quite a while now and she chooses a Walther P-22. However, as all of you will agree there are some concerns with that. First of course being that it's a 22. Secondly the fact that rimmed cartridges in a semi auto tend to present feeding issues. I haven't seen any mishaps with the Walther yet, plus I make sure it has CCI Stingers in it, but there's always a worry in the back of my mind that if and when she truely needs it, it will fail. Maybe I'm just too pesimistic. Although the worries I have, I would still prefer her to carry a 22 than nothing at all. But what I was thinking was to get her to go with a snubby DAO 22mag. Weighing out all the ups and downs, the only difference that's a real factor is that it holds 3 rounds less. She does not carry a reload, so at least she has more than 5-6 rounds like most carry wheel guns. But I feel like 8 22mags are better than 11 22lrs. Please feel free to voice your opinions on this matter as I will be sharing it with her. Thank you for any advice.
