Preaching to the choir, brother. The only semi-autos I own and carry are Glocks. I've carried and shot several others, primarily on the job.
I don't dispute that for many folks the ergos of other guns may fit them better and perhaps lead to better and more reliable shooting. Or that the other guns may be more attractive to them.
For me, I only care that the gun functions when I need it to and that I shoot it well enough for what I consider to be my purposes. The simplicity of the Glock combined with the lack of a manual safety and its reliability makes it "beautiful" to me. I consider it the gun I want with me if I get into a gunfight.
But I am not a gun collector and my purposes are purely defensive as opposed to recreational shooting. (The new Glock 44 might lead me toward some more recreational shooting in the future.)
To each his own. I'm happy with my choice and take no offense with what others may prefer.
