Yep, my brother and I both have one. I got the 7" and he got the 5" (? I think). I went for the longer barrel for sight radius and target shooting, but if I had to do it again I'd get the shorter barrel. His seems to balance better for me.
It's a one-off on a Model 41, but there is really a lot of difference. The 41 is the way to go if you are going to shoot any kind of serious (or semi-serious) competitive bulls-eye pistol shooting. Better slide, better trigger, better sights, but LOTS more money.
For the price I wouldn't hesitate to buy another one, but before you do, heft them both and think about the feel.
Can a guy have too many guns?
