I took the gun to the range last night and ran about 100 rounds through it and it did not jam once, so it looks as if the issues are resolved for now. I did immediately the gun was much easier to load and the magazine selector switch was easier to select from side to side, before the repairs it felt like it had to be forced to the point it would break. The action seemed smoother also. I put my sight back on and dialed it in at 15 yards, and will say this much for the gun, it is DEADLY ACCURATE for a short shotgun. With 00 buck I was able to put a hole dead center of the target and was able to then put every other round of 00 buck through the same hole at 15 yards.
Another good thing was that one of my range masters who was there the very same day I first fired the gun and had malfunctions, was there last night and he got to shoot the gun also and said it was night and day from when he first fired it. I will say that I am now happy with my KSG's performance wise so far, time will tell on the durability of the weapon.
