I am working on adding a wee lil bit of tension to the ejector- no extractor in my SA 5" loaded and I attempt a funtion test. I hold the hammer as I usualy do to let it down. It falls under spring power only half way! I only had the slide off the frame as I am working on the extractor and never pulled the trigger/safety group apart. Going to see a local mechanic for a smiths checkout but wanted to pose this delima for any coment or explanation. I didassembled and braught it all back together in working order. I just can't trust it right now.
