Does the TLR-2 /P30 hold a zero well.Well that would depend on the purpose of the laser....... I might guess that it is for self defense. If that is the case what is the most likely distance that you as the shooter feel confident to use that laser? Are you the only user of the laser equiped pistol? If it is for home defense / bedside gun what is the furthest likely distance it could be used? Also if you can achieve hits on close range high probability targets by index firing you may zero at a further range to take low probability shots. There is no one good answer to this question since it is an idividual decision based on the users own criteria. Keep in mind the laser is probably dropped and offset from the bore so only one distance will match exactly with POA and POI... the deviation will then vary based on distance. You can find a happy middle and call it good if you know what your criteria are. In general my CTC grip on my Glock 26 will keep hits on 6in disk from 15ft to 50ft since it is dropped and offset from the bore. My P30 with TLR2 will keep hits on a vertical 3x5 from 3 to 25yds because it sits directly below the bore and is not offset.
