I just got a "new" to me small frame witness with unknown round count. I followed Henning's video to disassemble and reassemble the pistol to give it a good cleaning. The previous owner thought that tree sap must have been a good lubricant because there was some serious build up on the pistol. Before I took it apart, the safety would not "click" on and off but other than that it seemed to work fine. Once I took it apart and put back together, the safety now "clicks" but now the hammer will not stay "cocked". The hammer now follows the slide back to de-cocked status. If I pull the hammer back by hand, it stays back and ready to fire. I am thinking that the sear had some build up on it that allowed the hammer to catch it but now that it is cleaned, does not have enough metal to catch the hammer. Or that the hammer had some build up and is not catching the sear. Any help would be appreciated.
Thanks
Mike
