Hi...
I am a dyed-in-wool 1911 type of guy.
Own a couple,a full-sized blued Springfield and a nickle Colt Combat Commander both in .45ACP. They just feel right in my hand and I have been shooting them for so long that the bullets just seem to automatically go into the 10-ring.
I have some experience shooting rental Glocks and one's owned by others. Ergonomics just aren't there for me. Accurate enough and reliable, just don't feel any thing for them.
When I went shopping for my first polymer handgun a couple of weeks ago, I tried several different polymer guns and the Glock didn't win the competition, even though I could have had a police trade-in at considerably less cost. I purchased a new M&P40, because it was the most ergonomic and the sights aligned better than the Glock.
If I feel the need to replace one of my 1911 carry guns in the future, I will replace it with another 1911 in .45ACP. When I pick up a 1911, my mind brings forth images of a WWI marine clearing a trench in France or a 1930s era private detective dealing with a gangster outside of a speakeasy. A 1911 just touches my soul...as someone said "A more elegant weapon for a more civilized time".
When I pick up a Glock, I think plastic...cheap and expendable. No soul...nothing to stir the imagination or memories.
