Diagnose that colt #1!


A pretty common question goes along the lines of: "my hammer won't cock back when I pull the trigger, 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:

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?



Removing it fixes the problem:


Fixing colts is easy!
