I can feel the bombs being lobbed at me already, but I will offer my opinion, from some one who owns both.
I have been shooting 1911's for most of my life. Currently still own one. I also own 3 Glocks all in 40S&W (22,23 and 27). Comparing Glocks to a 1911 is comparing night and day. Each are different. There is nothing like the feel of a steel framed 45 ACP 1911 in your hand. They shoot and point true and are way more accurate than most people behind the trigger.
But my wife will not touch the 1911 period, she is afraid of it. But she will stand with me at the range, with confidence and fire 200 rounds with her G-23. It took me several months to get her comfortable with the 23. And now when I am not home, I am more comfortable she can protect herself with her 23 if the need arose.
Anyone who argues about one gun being better than the other is entering into an un-winable argument. I love 1911's and will always have them. But I do love my Glocks.
Please no napalm
