I have a TCP and I have had one FTE in 300+ rounds fired. I believe this was because I had not cleaned the barrel/chamber after polishing the feed ramp as well as I thought I had; there was probably some grit left. I am led to believe this as the FTE occurred very early in the shooting session after I had done the polishing. After that, it ran another ~125 rounds with no FTEs. There was also one FTF, but I believe it may have been operator error.
That's two malfunctions in 300+ rounds, and I have good reason to believe that both had causes unrelated to the gun itself.
By the way, it fed Remington Golden Saber JHPs flawlessly.
