a Team Member of mine had lost his triggerstop screw but didn't discovered it.
He shot his match and then picked off for a gun check. Due to the gone triggerstop screw, it was possible to cock the gun with the spur, so the gun had a single action mode and was weighted.
Result: less than the minimum of 2,5 lbs. and he was DQed.
If he have had no spur, it wouldn't be possible to cock the gun.
What I have learned in the past:
The real reason of bobbing, skeletonising, numbering the chambers, coating, polishing, milling etc. is:
the gunsmith makes more money. My first PPC Revolver was equipt with all of that. Nice, but no winning gun.
I changed my gunsmith, one of the oldschool guys, and he build me a gun with no F/X but accuracy.
After that I realised an average of 1471.
