I respectufully disagree with this statement and I also don't believe there's meaningful equipment race in Prod.
I've shot Dave S's G34 and it's stock, except for the guiderod, springs and sights. I've felt some Angus-modified triggers and, while the SA stage is light, the reset is long.
If you want to go spend $ on tweaking your Prod gun - then fine - it's your choice. You're looking for a hardware fix for a software issue. Part of the fun of this sport is messing with your set-up within the rules.
Making the rules more strict will lessen gun diversity because more people will likely gravitate to the gun that's best suited - straight from the factory.
If you beat me, it's not because you had a lighter trigger or Bomars melted into your slide.
Can the rules be clarified - YES. Do the rules need major changes - NO.
