I had some work done and wasn't impressed. He installed a front sight on my 1911 and when he drilled the slide for the retaining screw, he drilled into the barrel. I didn't notice it until recently- it doesn't affect function, but it's sloppy work.
He also did work on another 1911 which came back with a barrel link installed incorrectly, so the pistol would fire out of battery. Luckily, I caught that before shooting it. He also charged me to install a barrel in the same pistol and come to find out it was a Storm Lake drop in barrel.
