Took 2 hours to finish the 80% frame and another 2 hours to fit and assemble all the parts. Total build time = 4 hours. 80% frame and jig = $350. Barrel and slide = $250. Internal parts = $200. Total Cost Minus Jig = $625. Building my own new accurate and reliable 1911 .45 handgun at home with simple tools = PRICELESS! Thanks STEALTH ARMS!
