I just bought a Ruger Blackhawk convertible (new). After the purchase I promptly measured the throats and then sent them to cylindersmith.com to get reamed. During the time they were in his hands I sat down and read the entire manual and on page 12 it finally mentions that if the serial numbers for the cylinders don't match then you shouldn't take delivery of the gun. Last night my cylinders arrived (I highly recommed cylindersmith, great work fast!) and sure enough the numbers don't match. They both fit the gun equally well from what I can tell but it looks like I have to call Ruger today and see if this is going to be a problem.
Anyone else ever had something similar? The 45 Colt numbers match but the 45 ACP cylinder is one number off (345 instead of 346). What really chaps me is that if Ruger fits a new cylinder to it, it will most likely come with a .450" throat again. Will they ream it to .452 if I ask them?
I realize this is my fault but I still think they should have put the note about matching cylinders before page 12 and even then put it in bolder, bigger lettering. Stupid me.
