I just acquired a soon to be returned M19 snub with a couple of issues.
Examining it after it arrived, I was dry firing it, comparing it to my other M19 snub and my M66 snub.
After a few minutes of gun handling, I couldn't close the cylinder.
One of the pins on either side of the cylinder arbor had come out and was trapped under the ejector star in some oily residue.
I was lucky to find it instead of losing it on the basement floor.
Then it became difficult to pen the cylinder, the latch requiring a very hard pull to open. Now it won't open - period!
What the heck is going on with this little bugger?
