OK, so I am one of the 1911 guys. Started shooting them cause my dad still had his, which his dad bought after WWI. Stock form (ok so the flat mainspring was replaced with arched and rear sight was replaced with the wider notch, in 1930's).
Firing std ball ammo it NEVER malfunctioned. Only when I loaded it with SWC's did I find I had to be careful about bullet selection.
Later I had a custom tuned 1911 that shot way better than I did (best group was less than 1" at 25yds). But, if it got dirty it would start to stovepipe (several hundred rounds worth of dirty).
So, today, my wife has a REALLY nice light commander that is a joy to shoot, and likes ball ammot too.
When I wanted another pistol I tried them all. I tried to like the Glock. It just doesn't feel right in my hand. The M&P was another interesting one. It seemed to fit the hand OK, but, when I shot it, it didn't feel right. I could not pinpoint what it was either. Wierd. And I fired three different ones. I ended up with a Springfield XD, full size. That one I like a lot. Fits me. No, it is not for concealed carry so it has the big magazine and longer barrel.
So, between the 1911 and Glock, I choose the 1911. Wife chooses it too, but, she insists on a Colt as well. Yes, she can be a snob
