The only Springfield 1911 I ever owned had serious feeding issues, couldn't make it through more than 3 mags in a single session without failing to fully chamber a round. I could fix it by swiping the feed ramp clean with my finger but it would only go for another 3 mags or so and fail to chamber again, and this was a $1200 lightweight operator model. It shot very well and had a lot of nice features (full size yet weighed 32oz unloaded, night sights, rail) but the feeding issues irritated me so badly I sold it. Having the feed ramp polished probably would have solved this issue but for $1200 I shouldn't have to do anything to make it function properly.
Now I own a Colt Rail Gun, series 80, and it can go 300-400 rounds without any cleaning, function flawlessly, and shoot at least as good as the SA if not better, I picked it up barely used (probably just one box of ammo) for $900. I say go with Colt, their biggest drawback is finding them for sale.
