I have a GP100 I picked up recently for $499 used but it's a 6". I really prefer a 4" for practicality. The gp100 is nice for $499 but when looking at a new 7 shot 4" at around $800 I realized I'm getting into the 686 price range. I think it's pretty much settled, I need a 4" 7 shot 686.

Thanks,
Bb
