I recently picked up the 629 revolver I purchased on gunbroker.com from the gunsmith. After only six rounds, the gunsmith informed me that the jamming was due to the cylinder being pushed back further than it should be towards the firing pin and that the whole firing pin assembly had to be remilled. He then told me that I should no longer shoot .44magnum cartridges out of it, because if I do, I should expect to be rebuilding it again in 250 rounds. This took me by a great deal of surprise, as I've never heard of any gun, regardless of the size of caliber, that was only good for 250 rounds. Just wanted to see what the rest of the community has experienced on longevity of these guns, and if I can really expect to be back at the gunsmith in 250 rounds. Thanks for the help
