God did create the design for the 1911 - then he sent Inspiration to John Browning who took the idea, ran with it and added a twist that made it completely for Man.
If you like the 1911, one of the nice things that is available is a .22LR conversion kit that allows you to change out the barrel and the magazine and shoot .22LR ammo all day.
I taught Mrs. JD how to shoot with a 1911 chambered in .22LR and while she had never really shot before, she took to it like a duck to water. She became so attached to the platform that HER first pistol was a 1911.
Now, if you like any other pistol, that is great, but for your FIRST pistol, I would recommend AGAINST a .45ACP is your primary practice piece. As you have discovered there is some good snap with the round and the cost to shoot it a lot can put a dent in your wallet.
One thing I can't stress enough is to get THE pistol that YOU are the most comfortable with, the one you will truly spend time shooting, practicing with and embracing.
Good luck and let us know what you end up getting.
