My conspiracy theory:
The 10 round magazine limit was secretly lobbied for by the gun industry, that way, they've been able to sell all the owners of the "wondernines" new .40's and .45's... Just wait until the 10 round limit is sunsetted...
More 9mms! ;-)
My 2 cents. Trama surgeons can't tell the difference between 9mm and .45 round wounds. They are both anemic compared to rifle calibers... So why do shooters get their panties all twisted over this topic?
If you sleep better with a large caliber, or feel better, go for it. The key is to keep shooting until the threat is gone. 2,3,4,10 whatever numer of rounds it takes, keep firing...
I find I shoot my Glock19 (9mm) pretty damn fast, not any faster than my 1911, but I vastly prefer carrying a glock vs. a 1911 due to weight, and the fact I have 33 rounds of 115 +p+ corbon available in 2/3's the weight of a 1911 w/ 15 rounds...
I feel pretty comfortable that 33 A hits will be enough stopping power for a mall ninja assult on my domicile... Your milage may vary.
The whole caliber debate is silly, and yet another tool designed to sell more guns... Which is OK, but whatever you go with, practice, and get good hits, that's all that really matters. The rest is BS.
Did I mention you can get 1000 rounds of Wolf for ~ 80 dollars at the local PDX gunshow? Lots of practice, and I now have money left over for the FAS 3 tatical course at Seattle Firearms Academy w/Marty Hayes, an excellent instructor in the NW.
I'd suggest getting training no matter what your decision.
