Hi all, I recently picked up a nice '59 Python with some blue wear but otherwise a sweet shooter. It's going to Colt's for a refinish and I plan on having them set the timing and action to factory specs. But there is a somewhat troublesome issue that comes up when shooting and even cleaning the gun after shooting. For some reason the cylinder will get harder to close than usual and the gun will resist being able to be cocked with the cylinder closed. The first time I noticed this I found a wire from an old bore brush had gotten between the star and the cylinder rear and was keeping the cylinder tight in the frame and cylinder movement in the frame was stiff. I got the wire piece out and everything was fine. Next time I went shooting and was cleaning the gun afterwards again and the cylinder resisted closing and I checked under the star, checked the ejector rod wasn't loose and it wasn't. I kept scrubbing and eventually it went back together again no problem but I could not figure out what the problem was that was keeping the cylinder from closing. I took the gun shooting again and for the most part it worked fine but a couple of times I had the resistance to cylinder movement. I opened and closed the cylinder a few times and when it was freely rotating I finished my shooting session with no further problems and I encountered no further problems with the gun after I got it home and cleaned it. All I can figure is this one is very tightly fitted with zero tolerance for the odd unburned grain of powder or other form of fouling. At least that's how it has behaved. One other issue is the sideplate screw coming loose just above the trigger guard. It's gotten loose enough the first time that it put a very slight marking around the cylinder. Since then I keep my eye on it but, will Colt torque that screw down to the proper specification that it will stay put or am I going to have to try some sort of thread locking formula to keep it in place? Thanks!
