Deathwind,

Please do carry a firearm if you want to, I always do. I am of the opinion that the .44 is more than enough with proper ammunition. Not necessarily the hottest. See Randy Garrett's (the former ammo maker)discussion at: http://www.garrettcartridges.com/defensive.html I think he has the right idea. On the other hand if you can handle the .454 quickly, it will certainly work. Just don't trade the power of the one shot for the ability to fire again quickly. I am not suggesting spray and pray, but repeat accurate shots if the first one does not work.

The SPOT is not a PLB, and although it can do some things better, at this point it should not be considered a replacement (see the many discussions from Doug Ritter). It is also, in the long run more expensive because you have to have a subscription where the PLB licensing is free. In just a few years the difference is gone.

Respectfully,

Jerry
