Last night I pulled out my 25-2 to clean it and The cylinder wouldn't open. I pushed the cylinder release as far forward as it would go, and was able to get it open with a light whack with a plastic mallet.

I took off the cylinder to make sure the ejection rod was screwed in tight, and it was. Put it back together and the cylinder still won't open. Can't pull the hammer back. I took off the cylinder release knob and it seems stuck. It will move toward the grips, but will not move all the way forward toward the cylinder.

Anything else simple that I should check before heading to a gunsmith? Also, if I need a gunsmith, anyone know of a good one in western Oregon? Any info greatly appreciated.
