Love this little guns look and feel. But right out of the box it was a problem. Failures to feed and eject, light primer strikes, this while trying 5 different recommended ammos. Sent it back to Taurus, 3 weeks later it was returned. “No mechanical or production defects, feed ramp was polished (which I had already done).” was all they said. The TUC is extremely ammo sensitive. 40G ammo is HIGHLY recommended. That leaves 22 defensive ammo such as Federal Punch pretty much out of the equation. I’ve got about 100 rounds through it. I’m told it will smooth out somewhere between 150 and 200 rounds, so for now I will feed it Velocitors and then see what happens.
