The 10MM is a great round but it is a round that seems to require a big frame. A whole lot of folks who need to carry just do not find the big frame natural or confidence inspiring. It's the same sob story the 1911 and other .45s have had to endure over the years.
Since so many police forces have to find a nice happy medium in order to accomodate fat, stubby and feminine hands as well as man hands, they compromose on the .40 or 357SIG.
In the end, effectiveness is only marginally at issue with 99% of these rounds from 9MM all the way to the big-bad 10. Hollow point rounds placed correctly are devistating every time. The want we all have is for a pistol to act like a 12 Gauge! And as much as I personally love the .45, it's just not a shotgun now is it?
Alright people, pay attention:
"To Many " is an address like in a toast or tribute while "Too Many " is an implication of excess.
I think I am the only non-fox guy out here!
