You are correct bubbinator. The major issue back then, but not the only issue, was the Colt Series 70 1911s came with an unthroated barrel. Throat the barrel, polish the ramp, tune the extractor, and with a good magazine, much of the problems in feeding disappeared.
The truth of the matter was, and is, that the real advantage of the 1911 was the single action "sear set", and the caliber. It was the fastest in the business, and although the Browning Hi-Power was a stable mate in the action dept. and more reliable it was in a "minor caliber".
There are MANY more reliable actions today than the 1911, and although Glock is one I could never get fond of, it is FAR AND AWAY a more reliable pistol, and a higher round capacity one also.
