I have a Browning Medalist (1968-70 vintage) and since the gun has been new I have had a problem with the dry fire device. When the gun was newer I could just reset in to the fire position. It was a little difficult, but I could reset it. How it is to a point that if it goes into the dry fire position I have to use a brass hammer to move it back. This has happened to me at two matches now and of course they will not let you take the time to “fix” the gun during a match. I believe the gun has to be taken apart and given a really good cleaning but I do not want to take the time nor I may not have the skills necessary to do this. I don’t want to take it to a Gun Smith because it is the only .22 match grade pistol that I have and I don’t want it tied up for a week of so. Has anyone ever had a gun ultrasonically cleaned? Any other advice till I get through the season?
