Hello from Oklahoma

I've been shooting handguns most of my life, mostly revolvers and mostly 357 Mag. I've had a few auto loaders over the years, but always rely on the wheel guns.
I have always wanted a 1911 45ACP as I believe the round is optimum for self defense and I like the 1911.
I now have a Springfield Armory Champion 45 ACP that has some major problems. I think the hammer/sear have been filed on and I know the springs have been cut, to the point that the gun is neither reliable or safe.
Through this forum, I hope to figure out exactly what this pistol is, what parts fit it and how to repair it.

Thanks
