Being a lifelong 1911 shooter, I came over to the dark side a few years ago.Try a CZ97.
Full size 45acp but it's more a staggered mag than a double stack.
It's bigger, but not overly so like the HK Mk23.
Still bigger than a 1911 tho, but damn is it rock solid reliable, accurate, and you can easily club someone to death with it when you run out of bullets (frame and slide are very solid steel).
I wish I could like my glock more....but it's so small my little finger has no room on the grip (G19) and it's kinda like shooting a cap gun or something, it just feels like a toy.
I put a Magpul magwell on my G19 and it keeps my little finger contained on the frame and adds a hook or ledge which plays an important role when drawing shooting.
