I carry one gun, a 627 when I carry on my person or in my car. I used to carry a .40 Taurus. It was far from fail-proof.

The 627 is nearly as fail-proof, high capacity, high/low powered that I need as a civilian. I do carry two moon-clipped reloads.

I plan on keeping the 627 in the car or the home and buying a 327NG for carrying due to weight, night sights, and concealabilty/size. I would only carry two guns, if I was anticipating problems with a known threat. Both of these guns would have to be the same caliber and loading system. Thus, 327NG and 627Pro are a nice match. Maybe throw a 627UDRPC as a third, but I guess I need another $2000 for a pair of smaller revolvers.
