This weekend I took my newest Tisas 1911A1 Army to the range and alternated shooting it next to my newest Colt Govt model. The Colt edges it out a bit in fit and finish, but they were pretty close in terms or accuracy and ease of shooting. The sight alignment on both was spot on.
I can't praise these Tisas (SDS) 1911s enough. I have 3 of them (2-5", 1-4.25") and plan to acquire more different models to try. To me the Tisas has just the right sized footprint in the hand compared to the added dimensions of some of my fancier 1911s. The Colt feels like an extension of my hand and the Tisas is pretty darn close to that, too. Your mileage may vary.
