I just purchased a PPS 43C today and took it to the range after cleaning. Does anyone know the strength of the standard recoil spring or where I can get a slightly stronger spring? The typical east block 7.62x25 seems to be a hot load. Looking at my brass, some of the necks are almost straightened and the brass is very dirty from blow by. Will a heavier spring alleviate this or is there something that I am missing. shooting at 25 feet(standing) it was very accurate with no malfunctions. At 50 yards shooting from a rest I had a few misfeeds. it shot very high and I had to bring the group down about 12". It was right on at 25ft. I like the gun and think it will be one of my fun to shoot guns. Thank you for your answers or comments.
