Thank you gentlemen for your responses.
Reins, it is too bad that your American Derringer had such a heavy trigger. Mine is crisp, but light. (The trigger on the 45/.410)
. I had been carrying a NA .22mag mini for years, and shot it a lot, and it was so easy to carry that the biggest danger might very well have been forgetting it was there in an emergency. This is to say that I was moving from a five shot single action to a two shot single action, so was already trained in the basic operation. I had carried the derringer like you said, for walks in the woods, fishing, etcetera. While it's size is easy on the pocket, I imagine scenarios that two shots with a slooow reload might be a problem. On the other hand, the first two shots are quite substantial considering size of the delivery system.
I also have to consider the extra time it takes to cock for single action to get it into action.
That is when I started working the .32 into the rotation. After having a chamber of.45 colt followed by one of the new .410 shells that have come out for the Taurus Judge in the bottom barrel, the .22mag just seems not enough firepower. The .32 from Kel-tec, I think, may be the next smallest and lightest option, next to the NAA mini. While the .32 round may be considered anemic, it allows for discreet carry, quick response of a double action triggered pistol, and greater volume of fire with the stock 7+1 magazine. My main concern for this choice is it's inability to penetrate hard tissue.
So, after lots of research, and gun juggling, I found the Rohrbaugh on the Internet.
It is going to be a while for the one I ordered to be made, hopefully before Christmas.
Until then, I am gathering holsters, gold dots, snap caps, and carrying the Pf9 when I can, and usually the .32 if I have to compromise.
I really do appreciate everyone's input, and can tell that there is quite a bit of brain power, experience and good info here. Thank you for the kind and gracious welcome, and I hope to be able to contribute to the benefit of the group.
Keep your powder dry, and God bless,
Griff
