I have the M&P 9 full size and compact. Have a permit, carry the 9c and use the full size mostly for fun at the range. They are both 100% reliable without a malfunction of any kind. I am thinking of a backup platform to have on my person or in my truck. Lots of thoughts on that mostly trending toward a revolver. This is a plan B in case the M&P 9c would fail...not that I ever anticipate that happening! I am not interested in a 380. The bodyguard 38 might be an option but I have seen too many reports of problems. Is a revolver the best answer or is there something I am overlooking??? Any responses are appreciated.
