Now that we've said more than we should have here - check out this link for some folks who have taken the "personal defense" topic seriously - http://www.firearmstactical.com. There's a report in there explaining pretty much the best round for the small pistol I carry. They also seem to prefer Doug's .40 S&W to a 357 SIG load. If anyone wants to carry a .45 around all day long be my guest, but one things for sure - I've always got my pistol on me because it's so light I don't even notice it's there. Rule number one for a gunfight - bring a gun. Regards, Keys
