Hey folks. I picked up a gorgeous factory nickel S&W model 13-1 a little while back that had been carried for the better part of 20 years by an air marshall. It is a beautiful piece with an amazing trigger but after about 50 rounds through I am having problems.

When I press forward on the cylinder release the cylinder is not falling upen like other revolvers I have owned. In fact it takes a GOOD amount of pressure to get it open. This gun was never fired much as he had an identical one that he practiced with. This was just for carry.

Any ideas on the issue? To me it seems like the spring loaded detent at the front is not beiing fully disengaged when I press the cylinder release.

No pics. Camera is packed and my Photobucket is down.

First thing I'd check is to see if the ejector rod was fully screwed in. I had a S&W that after several rounds, the rod would back out ever so slightly, just enough to cause it to bind when trying to open the cylinder.

This and gummed oil would certainly do this.

My first guess.

Yep, and make sure there isn't any crud under the extractor star.

Once again, Arfcom saves the day. Thank you for increasing my knowledge of revolvers gentlemen.

I have a model 28 that does the same thing but not all the time.   It's apart now except for the parts that have extremely small pins.  I don't have a punch to fit.  It's very dirty with some slight corrosion.  I'll clean it thoroughly and put it back together (I hope) and see what happens.

When tightening the ejector rod use extreme caution or you will mar the nickel finish.  Older S&W's have threads which are in the same direction that the cylinder rotates.  You may have one of these guns.  Shooting .357's in quantity will do the same thing.  And be sure to clean under the ejector star.  One grain of unburned powder will jam this gun up.  Use a good lubricant sparingly and you should be back in business.

Smith changed the ejector rods to left hand threads in 1959 and some around 1962 on their blue guns.  Stainless are left hand threads.  Not sure about Nickel.
