I have an older 4" 629 (-1), and ammo which is claimed to be 1200 fps from an 8" gun is 1000 fps from mine. Its a handful, even with those 240gr bullets going at "only" 1000 fps. It was easier to handle after I changed the grips, because the ones on it did not fit the gun very well (I bought the gun used so no telling what the factory configuration was).
If you want to carry, knowing what holster will determine whether you want 4" or 5".
