[ReZero after battery change DPP]

Just wondering if you need to rezero the Delta point pro after changing the battery? Or does it have some kind of memory of where the dot is...

[CO Rules]

Shooting Carry Optics with a Glock 34 MOS.  I have a few questions I couldn't find in the rules.  If anyone could help that would be really great.

 

1)  I am using the PMAG 21 round mags.  When doing mag changes sometimes they just take forever to fall out (usually on near empty mags) or sometimes they get stuck due to the lightweight.  Am I able to tape Lead weights (car tire weights 1/4oz) to the sides of the mag to make the fall out faster?  (The area where the mag body sticks out of the mag well.)  PMAG 21 rounds are already 140mm and they do not make heavier aftermarket base pads.  If I cant tape weights, then ill just get Dawson Precision extended base pads on a OEM mag.  Please provide rule for or against taping weights.

 

The only rule I can find pertaining to Carry Optics is:
21.7 Magazines OFM and aftermarket magazines and base-pads may be used. Grip tape and/or skateboard tape are specifically allowed on magazines and base pads.
