I'm considering getting a M29 .44 Magnum at some point. Looking to spend no more than $1000. I'd rather have a used pre 1990s one without the internal firing pin or lock...but I'm not above buying a new one if it's strong and is a good deal.

I am not familiar with .44 Magnum N frames as the only .44 Magnum I have is a Ruger New Model Super Blackhawk with a 10 inch barrel

My real question is whether I do the 4 inch or 6 inch. The 4 inch would seem to be more ideal for attempting to carry concealed and less bulky. A 6 inch, on the other hand, would seem to have better balance and more resistant to recoil as well as getting more of the Magnum powder burn and velocity. For 6 inch concealed carry is out, but that's now really a gun you want to do a whole lot of concealing anyway unless you are in a state or national wilderness park and can only carry concealed.

Thoughts, opinions? How much power do you gain or lose between 4 and 6 inch in a .44 Magnum?
