If you check the EXCELLENT link at post 49, compare the 1911 threads to the Glock/HK threads, and note the difference in the number of "My New Gun" problems.

The only problem I've heard of with Glocks other than the frame cracking issue with a certain model is the occasional problem with extractors fracturing.

You will find with 1911s that the most common problems are found in the non- fullsize models and it's always an extraction problem.

Now you will have manufacturing problems with certain 1911s but that's not a design issue but a quality control issue.
