I have a Colt 1991A1 that as near as I can remember was bought in 91' or 92'.. the quality is excellent. Especially the barrel.

It could be an anomaly. It's the only such pistol I've ever shot, owned, examined, etc ..

I shot a recent manufacture Colt Delta Elite a couple years ago. The pistol ran great and looked nice. But the mag release was way over sprung. Very hard to push.
