No there is not. Heck, I've shot the 4, 6.5, and 8 3/8ths S&W 29's, owned the 6.5, and have shot the 7.5 Supers, and, now that I think about it, even the 5 inch 629. The only one I've kept is the 4 inch, no dash 29, I bought in 1967.
Why ? Because it shoots. Try all six into 1.5 inches, that's outside spread, of Remington 240 gr. SP ammo at 35 yds. That, and it's the easiest to carry model of them all.
They do kick harder. But they recover faster. But there is a big difference in the felt recoil of an 8 3/8ths inch 29 over a 4 inch. E
