I have an sp101,and I've heard a lot about timing being a huge factor with revolvers. My thing is,I recently noticed that when looking straight down on the top strap,the flutes in the cylinder don't look perfectly aligned on either side. Now the gun shoots great,so my only thing is maybe the flutes were machined just a little off center between the holes? I mean were talking a very small amount,but its something that bugs me. There is very small amount of play in the cylinder,not enough to be visibly seen with my eyes but can feel with fingertips. Like I said the gun shoots fine,but its just something that I think about whenever I notice it,so is it a semi-normal thing for the flutes to be machined ever so slightly off center in a production gun.
Basically I just need someone to tell me its in my head and that the gun is fine.
Flutes, and bolt notches are important, with regards to timing, as to how the gun "locks up" prior to discharging a round down the barrel.
The hand should rise in to the bolt notch prior to the hammer falling. Where the flutes lie in relation to that is immaterial as they can be machined over the cyclinders or between them. I wouldn't worry about it if the gun shoots good and you're not getting lead "shavings." If you ever do get lead "shavings" you will know that gun is out of time.
