Think you have to take the reviews with a grain of salt, I bought a low end 1911 .45 acp frame from Fusion in Florida, right near my fathers house, in my Father’s Day he was a NM pistol shooter. A fairly decent one too, he had some old NM parts slide,barrel and bushing, we assembled a pistol it is so tight, no additional tightening was need none, my father is still raving about that frame!
