My question is on S&W N framed revolvers. A model 29 is a .44 mag. A model 24 is a .44 special. Both are N framed revolvers. What is the difference in the cylinder and barrel besides the .29 having it's cylinder reamed out a little longer? Are they of a different diameter, longer or shorter. Does the bullet have to jump any further in one than the other? Does one leak more gas with .44 spl loads than the other? I'm wanting the best revolver for .44 special rounds but .44 special revolvers are very difficult to find at a reasonable price. Where as .44 mags are plentiful. What are the facts without opinions?
