I don't play the IDPA thing anymore because I like to shoot. All those rules say to me is; when the Vtac is approved, flat face triggers will be legal in SSP. Too many Glocks with aftermarket triggers that look identical get by in SSP all the time. I did it when I shot SWIN a few years back. If it's an obvious replacement, then you just flip over to ESP. Not my rules, it's how the game is played.
