It was my first handgun. I don't regret it, but had I to do it over, I would get a 38spl+p. That's what I shoot out of it anyway. Accuracy is good to about 40ft. Way more than what you would use a "belly gun" for anyway. Cylinder length does come into play however. Longer slugs travel better than shorter slugs. They tend to mimic the length of the 357 round. The shorter slugs sometimes get distorted on their way to the forcing cone. I've read in past threads that cylinders do not lock up upon firing, and that the bullet lines up the cylinder to the forcing cone. Except for the colt that is.
Realistically, 38spl+p is max practical caliber for a snub.
