Interestingly, it seems weight is not an issue at all for most of you. Even the ammo for a 9mm or .357 does add to weight, let alone a full size semi or large frame revolver...
The fact that we can and do carry is why its the normal gun we choose. If its needed your going to want to have the gun you carry and shoot the most with you. Pack more than you need..... than need what you didnt pack. I may never need to shoot 60 rounds but if injuries or illness and dead cellphone happen its nice to have signal round available in addition to critter rounds.
