There was an owner survey years ago at 1911forum.com, that sampled several hundred pistol owners. It simply asked, "did your gun malfunction in the first 200 rounds?"
Glock ran about 11%
Wilson Combat 1911's were about 12%
Les Baer 13%
Colt 1911 about 17% (which included many different models)
Who won? H&K, with about 4% failures
I remember that. I used to be very active there.
