What does "aftermarket" mean in IDPA & CZ bushings from CGW

[IHAVEGAS]

Fiddling with a shadow 1 to be used for ESP division. 

 

I assume that since the rules say aftermarket safeties are a permitted modification (8.2.2.2 CC) I can use a Dremel to contour my safety to suit me as long as the safety remains functional - what do you folks think? As far as I know IDPA looks at "aftermarket" as being anything other than oem. 

 

Anybody know if there has ever been an official ruling on the Cajun Gun Works barrel bushings in ESP? I assume it is a clear no no for a ssp gun because of 8.2.1.3 A (Excluded modifications list - "Externally visible modifications the than those listed in the permitted modifications section" , it might also be a no no for esp because it is not listed under 8.2.2.2, but it is a subtle thing and I thought perhaps there had been an official ruling.

If it ain't in 8.2.2.2 you can't do it.

 

The bushing isn't on the list.
