I have a couple of 3rd Gen .45 Colt SAA with the removable bushing.
I shoot mostly 45 ACP in my autos and seen that Midway has the .45 ACP cylinders for sale, allegedly made by the same people that make the Colt cylinders.
I would like to be able to reload a couple of thousand rds of .45 ACP and use them in both the GM and the SAA.
However I have been informed by another SAA fan that the jump from the 45 ACP rd in the cylinder to the barrel is so long what accuracy I now have will go to heck.
My current .45 Colt cylindersthroat measures .455-.456 :-(. The barrel slugs at just over .451
I am looking for information from anyone that has used the.45 ACP cylinders in their .45 Colt SAA.
i have a 3RD generation colt SAA in 45lc with a 45ACP cylinder FROM THE CUSTOM SHOP made in 1996.the 45acp cylinder was fitted at a cost of $260.00 including the cylinder.you will have to look on COLTSMMF site for the new priceing......
My own experience with three different applications shows no appreciable difference.
A Colt factory-fitted ACP cylinder, fitted about two years ago when the gun was back at Colt's for another issue, works great in a 7-1/2" 1971 NRA Centennial (2nd-Generation, I think).
An aftermarket Uberti ACP cylinder works just as well in two Uberti-made reproductions.
The original ACP cylinder that came with my Ruger Blackhawk Convertible (from 1980) does fine, too. Both the Uberti and Ruger ACP cylinders have been milled down on the rear face to accept .45 AutoRim with their thicker rims, but still allow regular .45ACP to headspace as normal on the internal step in each chamber.
With all of those, there's no practical difference in point of impact or group size out to about 25 yards. Recent successful plinking at clay pigeons set up on a 100-yard-distant berm with the traditional fixed-sight Colt and replicas seems to bear that out at longer distances as well. Even the Ruger, with no adjustment to the sight setting, busted the pigeons.
At practical pistol plinking distances a .45 ACP cylinder should work quite well, especially if you're using factory ammo, since ACP is 'way cheaper than store-boughten .45 Long Colt.
This is only anecdotal info which may not prove anything in general, but for me, I use the two interchangeably and don't worry about accuracy: not enough difference, if any, to tell.
Get it and enjoy.
P.S.: That recently Colt-fitted factory ACP cylinder has a removable bushing, as well.

I think that a competent gunsmith could make you a .45acp cylinder and fit it to your revolver. The throat diameter could be set at .451-.452. In fact, a .357 cylinder could probably be rechambered if you wish and fitted to the gun. Whether this would be a situation that would pay you back is another issue. I can buy cowboy .45 Colt loads at the gun show for about $25 for 50 rounds. Of course you shoot reloads, so you are probably close to ½ that (less if you use cast bullets).

If you get a 45 ACP cylinder with the removable bushing, you will have no problem with it working in your gun that presently has that type of cylinder. There is a 45 ACP cylinder listed on GB or ebay now (forget which), but I don't remember if it has the removable bushing or not....
My biggest fear is when I die my wife will sell my guns for what I told her they cost.
What a strange coincidence. I was wondering if my 2nd. generation SAA (1960) was correct with the .45 ACP cylinder in it. Anyway, I took it out for the first time on Sunday and fired some factory ACP's I had and some of my own reloaded ACP and both of them shot far better than I expected. Sorry I didn't keep a target, (I stopped doing that years ago) but I can tell you that although I prefer my own reloads to the factory recoil, the ACP's shot extremely well. I was able to get 2" and under from 25 feet off a sand bag. I rested my arm on the bag. When I rested the butt on the bag I got decent groups but it shot to a lower point of aim.
All in all I'm quite satisfied with the .45 ACP rounds, and as a matter of fact, will keep it this way.
I hope that helps.

I think Colt will fit a .45ACP cylinder.
They do work pretty well note the ammount of Ruger SAs that come with both cylinders.

Mine is one of the best shooters I have. It started life as a .38 spl. I changed the bbl and had the cylinder rebored. Not sure if the factory cylinder will be as good (or better?), but don't worry about the 'jump in the cylinder' you mention. I also have a convertible Blackhawk that shoots better with ACP than Colt.
