Just a matter of choice
The handgun I shoot the most is my 1911. Why, because it just feels right. I have a Walther P99 that has the most perfect grip of any handgun I have ever picked up. It's chambered in 9mm, is less expensive to shoot, but I would still rather shoot the 1911. It may just be the culmination of all the right stuff; grip angle, trigger and components that a good many people find fit their personal needs.
I don't think it's any coincidence that the P238 (a tiny version of a 1911 design) is one of the top small gun sellers. WHY, because it just feels right!
