I had a new Wilson Combat that was hard to load from round one once, and a "wise guy" at the range said they need to be "worn in." I rolled my eyes and went to the safety area to get away from him, stripped it down, brushed it, wiped it with a silicon cloth and reassembled. Worked great ... nice accidental find. Now I clean my mags more than the gun (mostly because I don't drop the gun in the dirt every six to 16 shots).
