This decision seems to penalize safe-action pistol shooters more so than DA pistol shooters in Production. If this is a question of having the gun more like "stock", then the trigger weights should be adjusted in the same manner as other characteristics. For example, the weight restriction is currently 2 ounces over the factory weight (as opposed to one weight fit all). Instead, have something like pull weight cannot be less that 60% of factory weight.
A Glock going from 5 to 3 pounds does not seem like too severe a modification as compared to a CZ going from 15 to 3 pounds. If you take a CZ and reduce the pull weight to 9 pounds (which is 60%), that's offset by the advantaged gained by having subsequent 1.75 (or thereabouts) pound shots. I may not be 100% correct on the CZ trigger weight example, but it's close enough to illustrate my point.
I think that some characteristics can have a division wide ruling such as the current provision allowing replacement of the sights or barrel. But the mechanical difference between safe-action and double action are as wide as the difference between the weight of a Glock versus CZ.
A byproduct of this type of decision may also bring more production shooters into the argument as all production guns would be affected instead of one segment of the division.
My 2 cents...
