I have a NM Blackhawk that needs a 45 Colt cylinder, Can I use an OM cylinder to fit it. I've found a 44 Magnum cylinder that I want to bore out to 45, however, I don't know if it is a OM or NM cylinder. Will this work. The seller is unable to tell what edition the 44 mag cylinder is. Thanks for your help! Anyone has a 45 Colt cylinder for sale? Bought the gun with the ACP cylinder, guy had lost the Colt cylinder and at the time it was the ACP I was looking for.
