While you are entitled to your opinion, you are most certainly uninformed. With modern hollow-point ammunition, a 9mm Parabellum is a quite formidable cartridge. My personal carry weapons of choice are . 45APC, but I would in no way feel undergunned with a 9mmP with good hollow points. British SAS, etc. carry Browning HPs in 9mm. Defensive caliber pistols (9mmP, 38SPL, 357, 40SW, . 45ACP) are weapons you carry when you can't carry a long arm. None of them is exceptionally great at instant incapacitation. Being first to put rounds center of mass wins the fight.
For the record, I go with the . 38 SPL revolver. When the adrenaline is pumping, the last thing the wife needs is to have to rely on fine motor coordination to switch off the safety, or remember how to clear the weapons when it jams. I'm going to pre-emptively dismiss any argument about needing more than 6 rounds as superfluous, since most gunfights are at close range and involve 3-5 rounds fired.
She can't reliably rack the slide... .
AH64 you have lots to learn my young dead-eye.
Not everyone is willing to practice enough to be a member of the A team so a revo can make much more sense. Not everyone wants or can afford attatching, lights, lazers, and the kitchen sink so they look menacing at the mall. Not everyone can practice with light loads and then shoot heavy loads and not notice a difference. Some people aren't capable of manipulating the slide on every firearm some need smaller caliber firearms.
If you aren't afraid of standing in front of somebody pointing a 9mm hand gun at you then I bet you came from the shallow end of the gene pool.
A good friend of mine is working in IRAQ I asked him if he wanted me to send him any hollow points for his model 19 9mm Glock. His reply "Naw ball kills and I don't shoot anybody once. " Here is a professional that is happy with 9mm and ball to boot.
My preference on a home gun is an auto so you can throw a light on it. . Its very handy in the home...
A 9mm just doesn't have the energy I want for a self defense round. . I would rather have 13 . 40 cals than 17 or 19 9mm. . More is not always better... There is a reason cops went from 9mm back to . 45 or . 40.
I also get issued a 9mm, and I think it's a JOKE... 9mm Ball ammo. . yeah really scary with that. .
If your going to only have 1 gun, I don't think a 9mm is the best choice. .
Now personally I carry either a 10mm, . 45, or a . 380 Kel-Tec. .
One other option is to get a larger caliber and shoot light loads. . then put heavy hard hitting loads in it for defense. . and never fire them. . . in the heat of the moment recoil won't be an issue.
