Reading Global Village isn't going to change what happens in life.
People change parts. Maybe they believe they are buying OFM, 'production compliant' parts, maybe they don't.
It is extremely unlikely a competitor will ever be called on anything other than: trigger weight, Power factor, or something glaringly obvious, such as slide color or slide tape, etc.
No one is going to call you on a mag break or some other obscure internal part if it isn't obviously not OFM - I've never (in my short 3 years in the sport) even had the internals of my pistols looked at. Really, the sport and people involved in it have MUCH bigger fish to fry. (like keeping and attracting shooters that want to participate and volunteer for the sport), than to be concerned with spring 'B' that does absolutely doodly squat for added performance of the pistol. (IMHO, ymmv.)
