The light weight being a much easier carry, more concealable, and less of a bother. Though I'd love to have the same weight weapon in a stronger caliber, that is not yet here. I understand the freedom, but I don't see how that does not allow for our responsiblity as gun owners. I don't see how that drops accountability from our person. If there is a break in and the intruder has to make an effort to take a weapon, yes you are relieved of accountability.
Freedoms carry enormous responsibility.
If curious small children are not a factor to contend with, then the possibility of a break-in while no one is home must be considered. My computer is supposed to be smart, yet it hangs and freezes at the most inappropriate moments. I demand better from my personal defense tools. At any rate, the need to secure a firearm in the home is a necessary evil. It is prudent, just like you have an 'uninsured motorist' rider on your auto insurance policy or flood and earthquake insurance on your home.
