I selected the 9c over the full sized version because of size, without having fired either one.
The recoil of the 9c is not bothersome to me at all. It is a lot more pleasant to shoot than a 642 with non +P loads, IMHO.
Two possible outcomes, yes, but how about "crooks seize you, get your gun, and shoot you." ?
That would be my concern.
The idea is exceptionally stupid.
