For a defensive revolver, I don't see a need for SA capability. Its a point and shoot tool, not a target, or hunting revolver. I also carry in a Kangaroo, and I don't need a spur catching on my shirt as I draw. I practiced drawing with my 44 Bulldog when it was my EDC and the spur would catch all the time. I swapped to a spurless hammer, and the Bulldog would glide out. I'm now carrying a 7 shot 357, and I chopped the spur off that revolver.
To the OP. IF you buy a spurred revolver, and decide you want to remove the spur, you can still shoot SA at the range, for accuracy testing. WITH THE GUN SAFELY POINTED DOWN RANGE, CAREFULLY start to pull the trigger, then catch the top edge of the hammer with your thumb, and cock it. There isn't a safe way to de-cock a revolver with a chopped spur, so if you do this, make sure you can fire the gun, to drop the hammer.
