.I mentioned a G20 to you, but it was more in humor than anything else. The 10mm round is over-kill for SD purposes. When it comes to the power of a handgun, more is not always better, and the 10mm round has way more power than is wise for self-defense purposes........ and way more than is needed for the vast majority of LE purposes.
So why is a lower power 10mm worse off than a +p .40?
Not all 10mm is loaded to the bear killer stats.
