I can't do a survey, too many opinions I'm sure. Fire away!
1. Remington 1875:
I don't have a picture of an 1875 but it is better looking than its predecessor and that one is pretty nice.
2. Mauser HSc:
3. SIG 232:
You'll have to look that one up but it's just about as racy as the HSc.
4. COLT SAA:
Okay, this is a Charles Daly replica but it's as close as I can get:
5. S&W HEs generally:
Way too many pretty S&Ws!
Honorable Mention:
Walther PPK/S:
Ruger Bearcat:
