Hi, I just shot my TSO today, shot a hundred rounds, I only used 1 magazine with 5 rounds of different ammo 124gr. reloads & 115 factory. It might shoot all 5 or may 2 rounds before the trigger would be hard to squeeze & no discharge, I would take finger off trigger then touch trigger again & it would or would not discharge this even happen with factory loads. Not knowing if this gun was going to fire or not fire feels very unsafe. I sent this back to CZ.
