Pretty much this. If you like working on and maintaining things the 1911 may be for you. I don't use the term "tinker" because that has a different connotation. Sometimes we tinker when we should leave well enough alone. Like: why send a 1911 in for some smiths "reliabilty" package when the gun is running fine? If you think a fun Saturday afternoon is spent in the garage working on your GTO, you may be a 1911 person. On the other hand, if you just want to jump in your Honda Civic and go, you're probably in the Glock column.
Finally, there are those who just feel the innate John Wayne need for a "hard use 1911" who might be best advised to simply leave well enough alone.
