Hi guys, I recently acquired a 1963 python that was a duty pistol then sat in a safe for a very long time. I took it to the range yesterday and ran into a couple problems. First problem was the trigger had problems resetting, after firing a round it wouldn't go forward unless I applied a little pressure to the rear of it. The second problem was light primer strikes which happened more on .357 than .38 special. After a closer inspection I noticed the side plate screw looks to have been worn a little and the grips were sanded down smooth which makes me think someone may have worked on it at some point. After a little research I found that both problems can come from the springs being lightened or some old dried up gunk inside the action. My question is this, my local range has an ultrasonic cleaner, would that clean the action? Also I'm wondering if that would pose any threats to the finish? As of now there is quite a bit of holster wear. Thanks!
