I have a Tisas 1911 Stingray in 9mm. Haven’t had any issues. Three range officers have several different Tisas 1911’s and also have not had any problems.
Good luck with your new gun. Let us know how she shoots.
I have enjoyed the pistol and had no issues. I have ran around 500rnds and find it to be accurate and easy to control.
The only semi negative I found was the gun seemed to be stiff (not like the tightness of a custom) in the beginning but is starting to smooth out with use. All aspects of the gun and the purchase price made for a good deal.
