I live in a free state where I can carry any handgun I wish. I've carried everything from high cap 9mms, full-sized (and "officer's sized) 1911s, revolvers in many calibers, you name it. That being said . .
If I moved to the Left Coast I'd still carry the same thing though as my main CCW . . . a FIVE SHOT S&W Airweight. I shoot S&W revolvers incredibly well after all these years and I feel quite well-protected with the 5-shooter. It is incredibly light, conceals well and always goes bang.
Carrying a high-cap bottom feeder with the weight of 18 rounds or so of ammo is SO much heavier . . . and thus you might not have it on you at all times. A CCW weapon must be on you when trouble comes. That's why the rest of my old picks mainly stay in the safe . . . BUT it was hard to give up the big bottom feeders at first, so I decided to give the little airweight 30 solid days to make sure. That was YEARS ago now.
POINTS TO PONDER . . .
1. If you need more than five, don't engage! However, like birds on a wire, thugs scatter at the first loud report. Hit the first one and the rest will usually flee and leave their buddy to survive or bleed out.
2. Make every shot count, trust your training and your practice, and you'll be just fine.
3. OTOH, if a man can't hit the side of a barn I recommend a single shot . . . less chance of hurting or killing innocent bystanders!!!
4. Finally, shut off the TV. Hollywood has always made movies where guns are mostly full autos and even Roy Roger's six gun fired as many rounds as today's high caps. Hollywood is NOT reality!
Seriously, turn off the tv . . . get some good practice in at the range . . . shoot some serious handgun competitions and hone your skills and you won't need more than five (with a speed strip of an extra five if you feel the need). Better yet, skip the speed strip and carry an extra gun instead. This way, if something happens to your first gun you still have a gun!
