I can't speak for Ruger products.
But I have lots of experience with H&R convertibles.
I have a total of 12, with only i that is a double.
I have also bought and sold in the vicinity of 20 spare cylinders over the pst few years.
I have NEVER had to return anyone's money for a cylinder because it did not interchange with the buyer's revolver.
I also have taken all my cylinders out, and started changing them around with my own collection.
Only in one case did I experience any issues.
One cylinder seemed to be very stiff when trying to cock it in another piece .
I never tried to fire any of mine without using the cylinder mated to the gun.
with all the ones I have sold, I wouldn't worry about it, but, I just saw no purpose when I have the correct cylinders for all my pieces.
H&R also suggested to shoot only the cylinder mated to the gun.
I would estimate that all told I have tried, and sold 40 or more H&R cylinders to guns that were not the original pieces with only the 1 noticeable issue.
