I removed the side plate and lubed the ejector slide again. I also loosened the ejector rod and re tightened it. The cylinder now open's with out to much effort. Not sure what the problem was but it is working much better now. Thanks for all the help
The cylinder has been getting difficult to open for a while now. The rear of the cylinder will open some but ejector rod is sticking in the front on the spring loaded plunger. This is a 2.5 inch barrel. Any ideas how to cure this problem would be appreciated.
