Mike put the gun together in about 3 days. The final product was astonishing. Fit and finish were top rate. All the parts were installed and fitted. When shaking the gun empty with the slide locked back, there was no rattle. This concerned me as I wanted a very reliable duty gun. My concerns were later unfounded. Sharp edges were cleaned away. Trigger pull was good and crisp. Shooting. A quick 250 rounds. Strong hand, weak hand, limp wrist, upside down. Even ways I would never shoot a pistol. I did not see any point in ridiculous torture testing running it over with a helicopter or tossing it down a flight of stairs. The pistol was very accurate. It had no malfunctions of any type. It convinced me it would hold together and function to protect my life with. Bottom Line: The 1911 Mike built for me was very well done. I trust my life to this gun every day I go to work. That is saying a lot. It is accurate, well fitted and ultra-reliable. What else would you want?
