For the price, unless you have the knowledge and the tools to do a build, you would be better off to buy a mid-range 1911, Kimbers, Para, S&W, Springfield and a host of others build a good reliable pistol that shoot good out of the box in the 650.00 to 950.00 range. Just a cheap Essex frame and slide are going to run in the 350.00 range, and you got a long way to go from there, on top of that, if you used all so called drop-in parts, they are going to need some kind of fitting. When your done, you might have a pistol that shoots good or you might have a paper weight.
