The cylinder release on my 1968 Charter Arms Undercover (.38 Special) is binding. I am a novice gun owner, but an aerospace engineer with a notable amount of experience working with finely tuned machines and following technical directions and documentation. Since disassembling and doing a thorough cleaning didnít help right away, I purchased some new semiautomatic pistols (Kel-Tec PF-9 and S&W Shield 40). Now that I am practiced and carrying my semiautomatic replacements, I still want to fix the revolver. With the cylinder removed, and using some small tools, I can mimic a seated cylinder. The release functions without an issue. With the cylinder opened, the plunger works without issue. If I swing the cylinder into place and manually pull on the front of the plunger to mimic what the cylinder release does, the plunger sticks. If I jiggle it around a little, I can get it to open though. Pressing the cylinder release in the appropriate fashion also has a similar affect. It looks to me like something has gotten bent, even if it is ever so slightly. I canít tell what it is. The pistol received no obvious trauma. The pistol isnít a great pistol, but it was my first; my father gave it to me. I am not going to sell it. If anything, Iíll just preserve it and put it in its 1968 original box, and keep it in the safe. With that being said, if I could fix it, it would be nice to have yet another functioning weapon available. Any advice? Thank you. I apologize if "plunger" or any other descriptor isn't the appropriate technical name. I don't have my manual with me at the moment.
