I have about 800 rounds through mine and it seems to run fine most of the time. It ocassionally will bind up (about 5 times now), locking the slide back and it's difficult to get it back in battery . I haven't been able to track down exactly what's going on, because each time it happened, I was in a competition. It's still a lot of fun to shoot. I recommend it for a range gun.
I had tweaked trigger to 3.5lbs, and lapped the slide/frame, and later "peened" them to tighten it up some more.
Tried various Match grade factory and reloaded ammo. Different bushing, fitted a Kings NM S/S bushing...................
No Joy !!!
I asked Dave Williams with cthe ustom shop about it. He said it was "Nominal" accuracy for a OTC gun/barrel (over the counter- I won it in a league competition).
Ditto re: both ramped and unramped barrels.
Both are equally reliable and accurate (or inaccurate).
The reliability issue in feeding is a function of the magazines. With good mags, all mine worked well.
Springfield makes the 9mm with both the ramped and non-ramped barrel. They have the same order number. However, the one with the adjustable target sights comes with the non-ramped barrel and the one with fixed sights comes with the ramped barrel. The one with the non-ramped barrel will not consistently feed well. I have sent mine back to have the ramped barrel installed. A friend did the same thing. As a side note, the Kimber 9mm comes with a ramped barrel.
I can imagine that the unramped 9mm guns don't run well. The stock 1911 feedramp isn't designed for 9mm ammo and I doubt SA re-designed their frames with an integeral 9mm ramp. I think I'd want the ramped barrel (its for a 9x23 conversion anyway).
I thought Springfield stopped making the fixed sight version and now only made the target sight gun. Why must they make things so hard...
