The first three bullet points seem pretty non-controversial. The last point appears to primarily rule out shoulder holster and possibly purse draws. IWB/OWB and ankle carry all point the gun towards the ground near the shooter, minimizing the chance of sweeping anyone. This may not free things up as much as some would like, but I think it is a good change.
Did you get to hear any of the discussion of the rule change? Was the last point put in for the reason you suggested? I don't use a shoulder harness or purse so I'm just curious about it. Theoretically, someone could just get on their knees with a shoulder harness or purse and do it that way.
Drawing from a Holster:
- Safely drawing from a holster and firing is allowed in the bays only.
- Drawing from a holster on the main firing line is not permitted.
- Safely drawing means that throughout the draw process, the muzzle is always pointed directly at the ground or into a berm.
- Only holsters that hold the firearm in such a manner that the muzzle is pointed at the ground within one meter of the shooters feet are permitted.
