None yet so far, I have shot about 200 rounds though it so far. I am just using the official magazines. No hollow points though it yet. The only problem that I had with a clip was when I slammed it in my sleeve got caught in the bottom and I had to pull the clip out and put it back out again.Have you ever had a jam Nodle (with your 4595TS) ? Have you seen some magazines give issues over others? Have you tried hollow points?
