Just scanning the thread and noticed most folks using or carrying bugs are using an auto for a primary. I'm a revolver CCW, .357 SP101, exercise it often, don't see a need for a number 2. I also believe if I can't settle a gunfight in 4 shots or less, I'm the looser.
I hate to say this, but with that outlook YOU ALREADY LOST!
If I am ever in an "armed encounter" again I will be fighting and taking the fight to the assailant, like I did in the past. Now, don't misunderstand me, taking the fight to the assailant could very well, and most likely does mean, getting behind cover. I carry revolvers because I like them, but because I have two of them I have almost as much firepower as someone with an autoloader.
When I am fighting because I am in fear of my life I get very MAD! That is what I mean by "taking the fight to the assailant". How dare they try to harm me! As far as being "Dead Eye Dick" don't count on it. If it happens, great. Chances are you will miss more than you hit, just a "statistical" fact.
As far as one gun for carry goes, ask yourself what you would do if your arm was otherwise occupied? Your Primary hand/arm is busy deflecting a knife. Now what are you going to do to stop the threat? Your SP101 is a great weapon, but a little on the small side for my taste. I carry a 4" N-Frame because if the SHTF again I want every advantage I can get. My BUG is a little J-Frame.
The revolver is not an advantage, IMHO, I just like them and I'm vain enough to think they are "cool", also, I do shoot them better by a small margin.
