The J-frame for sure is enough for John Doe ccw. If I was active L.E. and or on a Swat team I would have a M4 and g17 and a J-frame in the pocket or vest or on my ankle. Most average people that CCW be well protected by a J-frame,but then you have web commando's that are scared to come off the front porch without a hi-cap and 3-4 magazines. Street smart's and good sense will get you a lot farther in the real world keeping you from getting shot. Godbless
