Well, thanks, Jwhitmore, I will look into that a bit more.
I did speak to Ruger and they will NOT fit a 45 ACP cylinder to the gun. Oh well, I'll just have to do two types of loadings for the Colt. They also will not fit a new cylinder to correct the offset issue.
Ruger will not install a 45 ACP cylinder because it is a limited production item but occasionally you find them offered for sale after market. A New Vaqeuro ACP cylinder is too short and smaller in diameter for your Vaqeuro frame due to the smaller frame of the New Vaq. So if you find one, be sure it's the Blackhawk/original Vaq. size.
Ruger will not fit a new cylinder to correct the 'offset' issue because it has nothing to do with the cylinder. The offset is caused by the position of the cylinder pawl (hand) which controls cylinder position based on hammer position. Since New Models load with the hammer in the down position, the pawl is not in the correct position to allow the cylinder and chambers to align with the loading gate. That's why a freespin pawl or half cock hammer was suggested.
The new Vaquero and Flat top Model guns that align properly have a free spin pawl and a hammer-slot-mounted detent which aligns the cylinder and chambers. I have duplicated that in my original Vaquero by purchasing and installing the parts: pawl $30, detent screw, spring & plunger about $3 from Brownell's. Half cock hammer eliminates the need for the detent but is about $100 and needs some fitting to allow the hammer to be cocked when the loading gate is open. And although it adds a step to loading and unloading process, it does give the Vaq an old time authenticity and feel. Your choice.
Since it's impracitical to use 1/2 moon or full moon clips in your revolver anyway, and to eliminate the need for a separate cylinder in 45 ACP, you can buy or load 45 Schofield cartridges rather than using small volume powder loads in the 45 Colt long cases. And by trimming the Schofield brass to ACP length you can duplicate 45 ACP ballistics by using ACP loading data. As you know, 45 Auto Rim cases will not work due to the fatter rim.
You can even buy "Cowboy 45 Special" brass and loaded ammo, a new cartridge which is already the exact same legth as 45 ACP. Go here:
