Correct, Don, there are a lot of modern 1911s out there but they're not the least complicated to me due to the years I've spent with them. I can't say the same for the early 1911s since I wasn't interested in the collecting end of things but in shooting them. As you say, not having a parts numbering system like the Luger makes it harder to know what you're getting.
On the other hand, the Luger is a whole new thing to me and trying to wrap my head around so much makes them complicated seeming. Someday I hope to get to the point in my Luger experience where I'll look back to this time and chuckle at how it could have seemed so complicated.
For instance, why is the German word "gesundheit" on the thumb safety since I believe it means health?
