Normally, I would agree with this. However, 5k or so rounds on a Gen5 G17 with absolutely zero light strikes on a 4# striker spring with the stock striker has changed my tune. Winchester primers, Dillon 650, sample of one, YMMV, yadda yadda. I did recently replace the spring as a preemptive measure, since the trigger was starting to feel lighter than I felt necessary.
ETA: A couple thou rounds on a second G5 G17 and five hundred or so on a G5 G34 as well. Same trigger config, same ammo, same reliability.
