Sent my TCP in for repair had FTF and FTE probs slide release was froze could not get it to work unless forced down with a flat head screw driver and slide was grinding on the rail. Well got it back today and the only thing that was done was the 1 mag I sent them they bent the lips on it and called it calibrated now it double feeds. Also the person I spoke to I told my probs and put a letter in the box. Now I have to make another 40 or more mile trip to drop it off to the nearest Fed Ex.
