Ok, so I have a TLE RL II and it is great, 100% reliable with Novak Mags. I have had no problems with the Series II parts, but I felt like trying the test you always read about on here where you turn the pistol upside down and cycle the slide slowly. Well, the slide stops about a quarter of an inch out of battery. It doesn't do it if I let the slide cycle at full speed, but just out of curiosity, what and how do you polish to fix this? I know it isn't really a problem and has never caused any malfunctions, but I was just curious.
