It depends on what you plan to use it for . . . and if those plans involve toting a big, heavy roscoe on your person through the mountains out west or the hot, humid swamps of the Okefenokee Swamp down South!
The main thing for me is that if I have to pull my revolver to shoot something while hunting, I do NOT want to be surprised if the gun doesn't shoot.
This would be fatal in a charge by a Grizzly bear . . . or an attack by a two-legged predator you surprised in his hidden forest pot patch . . . AND a real tragedy if a 200 class trophy buck passed by too!
Thus, I'd have to rule out the 460 revolvers, as well as the 629 revolvers too made after the switch to the damn internal lock in 2002. Too many reports documented in the past on this forum and others where folks had the little flag rise to "half-mast" and see their revolver lock up like a stone in half-cock.
Nawwww . . . I want to be able to count on my revolvers to ALWAYS go bang! Some here say it doesn't matter. Many of us say it DOES.
That all being said . . . I like the lighter weight of the N frames . . . plus you never feel the recoil anyway during a hunt or a fight. Plus, for my needs, my 6" Model 29-5 has always gotten the job done for me in the woods for many years now . . . and the 29-5 model has the same endurance package given to today's 629 revolvers . . . basically a gorgeous 629 without the damn weep-hole on the left side.
I guess I'm saying . . . don't rule out a fine USED 629 (or any Model 29 from the -5 forward) without the lock. You'll save money too! Here's my 39-5 with the longer bolt lock up slots on the side of the cylinder (longer to the front of the turn ring) of some of the M29-4 and all newer (29-5 & forward Model 29 revolvers with the "Endurance Package"), including all the 629s ever made too:
