For all those suggesting 5-shot J Frames, I appreciate your input, but is that really the gun you want for a gunfight? It's a serious question, not a criticism. Size and weight aren't going to be the deal breaker here for me (within reason--I'm probably not going to opt for an N Frame with a 8 3/8" barrel).
If somebody was waiting for me in the parking lot and the fight was on, I'm thinking I'd want a real rear sight--not just a notch, and bit more grip than the typical 2 finger. How much sight radius would you want? I'm talking in terms of fighting back against a determined attacker.
Thanks!
You might like the S&W 337-1. 3" barrel, excellent sights. I have one. Nice gun. Google 337-1 to see a picture. They are hard to come by, but available on occasion if you look.
