I've had my ProTsc 1911 for a few months now and after aprox. 10,000 rounds it is still doing very well. Mines set-up with the black hogue grips and Shield Mini Sight.
To anyone looking at getting one I can certainly recommend fitting the magazine bumpers and buying twice as many mags as you think you'll need
As for accuracy, last week at 20 yards LSR I shot an 85 unrested with it, using a Shield Mini Sight; so certainly no complaints! It seems the more I use it the sweeter it shoots.

I did however find within 50 rounds that I prefer to shoot it without the TSC black dimpled barrel shroud, so I'm looking at selling it. It cost me £55 + post and is mint, so I'm asking £40 posted. Please pm me if interested, to avoid messing up this great review thread.
