There is one other thing you might want to keep in mind whenever you change a cylinder in the Colt SAA. Where a lot of people would call this headspace, it really isn't. What it really is, is the distance between the rear of the cylinder and the front of the recoil shield. This space must be kept within the allowed tolerances. This information isn't mine by the way, it's in Jerry Kuhnahausen's Shop Manual on the Colt Single Action Army.
The information below is what's in the shop manual by Kuhnahausen:

The cylinders are to spec. It doesn't make a difference between the bushing types. Long as the head space is correct like stated above and lock up is no different than the original. I placed 2 45acp cylinders into two of my shooters and they work just fine.
I have a relic SAA that I purchased a bit over a decade ago. It was stated in the description that it been found in some ruins in New Mexico, and had been left out in the desert for perhaps 100 years or so. It's plain a bit of "restoration" was done - the grips were replaced and I think a new...
I had this one put back to the original barrel and cylinder and had the trigger sear repaired to make this one safely shoot. I will have period dated grips installed and a Colt letter on the way ! Thanks for all the input on the original post
Just came across this at a LGS as it had just come in. Notice on closer look that the frame and cylinder #s match in the 100XXX serial number but the grip is actually from the 229XXX range. Won't be able to do a function check until I go back with some gloves but, off the top, what does...
I have recently seen some late model SAAs with serial numbers close to S89000A. What is the highest you have seen from recent production?
The newest SAA I have was made in 2014 and has serial number S63193A. The highest serial number I have is S66265A which was made in 2012.
Anyone here have...
