I submit its a Service-Six not a SP101, but thats semantics. kick ass just the same!  ;)

The OP later clarified it is a GP-100 (Service Six revised-ish) towards to end of page one.

But it is a sweet gun either way.

I agree that no barrel/cylinder gap should be .012", but it is my understanding that even if none are now, some used to be.

Freedom Arms generally ranges from .002"-.003", but that's really tight!  I think most Ruger revolvers are around the .006" or so you mentioned.

I measured the cylinder gap this weekend - A .004" gauge would fit and a .005" would not fit.
So .0045" it is.

Those 10mm Mag numbers are great and I am still amazed at the efficiency of the Blue Dot powder, at providing  good numbers whit reasonable pressures in most any cartridge/bullet weight combination!  :D

Thanks for posting the actual measurement.  Based on all I've heard that's relatively impressive.
Gun Control?  Oh yes, the theory that becoming a victim is somehow morally superior to defending yourself & your family.  Makes perfect sense.

Clements Custom Guns also offers this conversion on the GP100. Been thinking I may need one.
