Reloading the .45 ACP must be one of the easiest rounds around. I shot in a league years and years ago and almost everyone reloaded the same...a 185 grain or 200 grain lead semi wadcutter with just enough Bullseye powder behind it to cycle the action of your particular 1911.
(Check out your particular gun to see if it will reliably feed lead semi wadcutters-some guns do have problems with them.)
I don't give out reloading recipes because I can't trust my fat fingered typing and I'd eventually give somebody a combination that would cause 'problems'. Almost any reloading manual will get you the information you need. Bullseye is a bit on the dirty side but seemed to give VERY accurate results.
Good luck with your new gun.
P.S. For a while I used Red Dot powder because my father was a trap shooter. He looked at how much he used for a case of 12 gauge shells and how much I'd use for a box of .45 ACP's and laughed out loud. He said I could have free powder if I'd load a case of shotgun shells once in a while (he had a MEC 650). A great deal all around until I moved away. I found Red Dot to be even dirtier than Bullseye though.
P.P.S. I've never used it but another wildly popular powder for the .45 ACP is Winchester 231.
Here's a link to an article from 'Guns and Ammo' about reloading the .45 ACP.
