watch what you are doing on the reassembly, and follow the directions in the FAQs. Last year I had left a revolver out in the nylon fender bag on my four wheeler all winter, and spring. I found it during the summer, after it had been rained on many times. I disassembled it and took a wire wheel on my grinder to it to clean all the internal parts of rust. When I reassembled it I got one spring out of position. The gun would only turn the cylinder if I pointed it up when cocking it. Otherwise the cylinder just sat there when cocked. I took it apart several times and had a brain block. Over a period of several weeks it almost drove me nuts. I kept missing the one spring out of position. Took it to my gunsmith, he laughed and said he knew what the problem was before he even toushed it. He disassembled it to the point he could remove the spring and showed me how to reassemble it correctly.
