Bought a 629-4 .44 S&W Mag from a fellow member here and it has been sitting in my safe for a couple of weeks. I took it to the range today and put 12 rounds of light target loads for a warm up. I noticed that after the second cylinder full of ammo when I went to open it, it was a bit hard to open. I put in some winchester factory loads and same thing when I opened the cylinder to dump the empties out it was really hard to open. I removed the ammo and thought I better stop and figure out what is going on. Looking at the cylinder and frame everything looked like it was in order. I closed the cylinder with no ammo in it and it was much harder to open this time. I closed the cylinder again and now I can't even open it. Any idea's?
 
The ejector rod thingy is likely coming loose. It's a reverse thread, if I recall, so you'll need to tighten it the other way (lefty tighty, righty loosey!)

I make sure the rod is tight on my 686 every time I take it to the range...

Anyone else care to verify my guess?
 
Exactly. I was trying to get the cylinder open and as I did I noticed that the rear was loose and the front was binding. After scratching my head (bald head, i don't scratch to long) I figured out how the end of the ejector rod was held in place by a pin under spring pressure. I went to my gun parts book and noticed that the rod was removeable because it has threads on the end and pushing the rod from the other end (where the ammo goes) I noticed that there wasn't enough clearence to unlock the front pin. I turned the ejector rod and found that it is left hand threaded and when I tightened it up, bingo it works. Never had this happen before and I have had a model 28 for years but obviously I have never taken the ejector rod/cylinder apart.

Canucklehead: would you advice using a green color locktite (easy to remove type) or just simply thighten before each shoot?
 
I wouldn't use locktite... just make sure it's snug before shooting.

To be honest, I've never had mine come loose, but I always make sure it's tight!

Holy crap! I helped someone!!! :lol:

The above solution should work .Had the same problem with my 629 .
 
When you get the cylinder to release take out the number one screw, closest to the barrel, slide the yoke and cyl. off. Place six empty casings in the cylinder and tighten the extractor but not too tight, remember reverse threads. Just snug it up.

I'd agree with the above; likely the ejector-rod unscrewing on you, but it can also sometimes be a symptom of material (loose powder, etc.) caught under the ejector-star.
