While many people talk of slide to receiver fit, one of our resident THR experts asserts that said fit would reasonably account for not more than approximately 5% of a 1911's accuracy. This resident expert maintains that the critical link for the 1911 is the barrel to bushing fit.
In my own experience, having owned more than a couple dozen 1911s, I too have found this to be the case. The most accurate 1911 that I own is a rattle in terms of the slide to receiver fit. However, the barrel to bushing fit feels more like a steel monolith, than two pieces of steel fit together.
So, here is my request: post a picture of your most accurate 1911's barrel, showing the wear pattern that should be indicative of the barrel/bushing fit, and consistency of the fit (contact).
Feel free to add comments, for example, about the slide to receiver fit, the make, model, or other as you see fit. This thread is not intended to serve as a slam against any pistol manufacturer. I am looking for excellent performers, regardless of the make, model or caliber.
Thanks,
