Well, I DO like the Model 29 .44 Magnum, most of these have in excess of 10,000 rounds fired through them:
The 6" Full Lug barrel was originally an 8 3/8", cut to 6" by Memphis gunsmith Bob Mason.
Incidentally, the first long barrel .357 Magnums (Pre- Model 27s) had 8 3/4" barrels. These provided a sight radius longer than specified by the United States Revolver Association (USRA) so the length was shortened to 8 3/8" to comply with their standards. More than you wanted to know, I'm sure.
