I found a 1970 Model 36 in beautiful shape today, and took a chance on it. When you open the cylinder, it stops about half way down, as if it's falling into a detent, and then requires a little tug to get it completely open. The same thing happens when you close the cylinder. It stops about half way up, and then needs a little nudge to get it past that resistance so it can then be closed shut. I own lots of Smith revolvers, and this is the first time I've encountered something like this. Is this something to be concerned about? As I've played with it a little, it seems to be loosening up a bit.

Thanks in advance for your responses!
