Pretty much.
That is pretty much it and it could work just like that.
However....... The very heavy recoil spring and the very powerful round contributes to a large increase in slide velocity.
This can cause problems with feeding. Make sure your Mag springs are strong would not hurt to replace them with Wolf extra power mag springs.
This will help to ensure the mag pushes the round up fast enough for the slide to pick it up correctly.
Additionally if your gun does not have a Fireing pin safety make sure you have a strong fireing pin spring to prevent slam fires. The extra power recoil spring will probably come with one.
Ensure you use 45 super brass not regular 45 brass if reloading.
Make sure your New thicker stronger recoil spring does not cause spring bind and break the bottom off your barrel bushing.
OK fellas what did I miss?

One Caveat
Have the gun checked for locking lug engagement before you make the switch. You'll want all you can get to allow the lugs in the slide and
barrel to live long and prosper.
I'll never forget the look on my brother-in-law's face when his sheared
off on a .451 Detonics drop-in conversion that he did...in spite of my warnings...
I think it hit the 500 round mark before everything let go.
Luck!

how does 45 super compare to 45 acp and 45 acp +p?

185 grain JHP 45 ACP usually runs around 1000 fps
185 grain JHP 45 +P usually runs around 1150 fps
185 grain JHP 45 Super can be loaded to about 1400fps
230 grain JHP 45 ACP usually around 850 fps
230 grain JHP 45 +P usually around 950 fps
230 grain JHP 45 Super can be loaded to about 1100 fps
It seems to be a pretty impressive round and I am thinking my S&W 4506 is just the ticket for this cartridge. There has been some discussion about Starline's 45 Super brass vs. their 45 ACP and +P brass. I would certainly want some way of visually discerning between 45 ACP loads and 45 Super loads and a different headstamp could be the ticket.

Does any manufacturer build a pistol already stressed for the .45 Super and is it availible as a factory load?

seems like maybe Spld did, at one time,
anyway. Why not just do what the .44 mag guys nearly all do? Practice with a .45 ACP type load for 90% of your shoot, and save the hot stuff strictly for taking big game? At the few score rds a year that that entails (to include practicing to control the hotter load) the 1911 will last you for many years. I'd include a neoprene Shok buff, and I'd section a couple of cases with a Dremel cutoff wheel, and measure their webs. One in .45 ACP, one in Super. Then make up your own mind about .45 Super cases being any "stronger".
