I have not read the referenced thread, so I'm not sure I am taking the context correctly, but...
In my opinion
, with the proper practice and instruction, the average shooter can become proficient with most any well designed, quality handgun.
That said, some people are drawn to a certain design and "click" with it. In my case, the fist handgun I ever fired was my dad's WWII 1911, when I was about 8 years old. I did not fire it more than probably three-four rounds total. He sold it shortly thereafter, and my folks split up not so much later (maybe she booted him for selling the 1911
). I didn't pick up another handgun until I joined the USN in 1977...and guess what that was?
Again, I only fired the few familiarization rounds, and again didn't pick up another gun for another five years or so.
When I went to buy my own first handgun, guess which way I went?
Since then I have bought/tried/carried/sold a bunch of different designs. What do I shoot best? Take a guess.
What do I shoot second best? Surprisingly (to me) an S&W K/L/N-frame. I had only shot a revolver a couple of times, long ago, and neither experience was very positive. However, in the last ten years I have owned several and like them quite a bit. Just goes to show, life can take some strange turns.
Hope this helps.
