How significant is the slide to frame fit on the accuracy of a 1911? I've read a lot of conflicting information about this. Some argue that, since the sights are on the slide, all that matters is that the barrel and slide have consistent lockup, and that slide to frame fit is purely aesthetic (i.e. has more to fit and feel than performance and function). Others argue that slide to frame fit does indeed matter, as it is essential to achieving consistent lockup. So, what says 1911Addicts? We have some top notch smiths here, as well as some with extensive experience shooting a wide variety of 1911's. I'm curious to know what you guys think. Has anyone done any kind of meaningful side-by-side comparisons?
