Don't own one but have fired 2 different models. 2 mags through one and about 100 rounds through another (the owner was very kind). No feeding or ejecting issues and they both went bang every time. Both had very tight slide to lower rail slides. The finish isn't 100% but its not bad either. Both were accurate iirc but think I was only shooting at 15' or so. You can't go wrong with one for only $400 bucks. It's a sturdy handgun and I don't think you'd be disappointing as long as you know its not an $800 or more firearm.
Thought about buying one 'for the price' but we had been looking at the Ruger SR1911 for sometime. A visit over to see Chris last Dec resulted in a SR1911 CMD coming home with me and have to say I do like it better then the Tisas. I've now put 750 rounds of .45acp through it without any issues. Wife simply loves it! Thanks for 'holding it' for us Chris.
Again, for only $400 bucks it is almost a steel really as from what I've seen for myself and others online its a reliable firearm. It simply doesn't have the 'upgrades' the more expensive 1911s have.
