A pretty common question that comes up: "my hammer won't cock back all the way, what's the problem?!"
It was only a matter of time, but it happened to me. In this case on an m357 that I had tuned for my dad. Fortunately it only happened when I checked it after getting home so he's none the wiser.
So: any guesses for what went wrong here? (For what it's worth, I got it wrong.)
Here's a photo showing the maximum distance the hammer can be cocked:

Answer below after a bunch of line feeds :)
So openeing it up, looks like a strange piece of metal has lodged itself:

Closer: seems machined almost:

Nothing seems broken off though, so I'm guessing that perhaps it was lead. Not sure how it'd get in there --- maybe when it was laying on the bench a fragment landed in there? Puzzling. It wasn't in there when I put the sideplate on:

Removing it fixes the problem:

Fixing colts is easy!
