I watched a latest generation G17 mag with latest generation OEM +2 baseplate with insert and 11 coil spring fail on the range the other day. The mag was fully loaded. I went to load my G17 with it and when I racked the slide the mag fell straight down. I must not have seated it fully. The mag probably hit the ground baseplate first, but I'm not sure. The whole thing exploded, throwing the spring feet away in one direction, the follower in another, and rounds everywhere.
I examined all the relevant parts and nothing seems to be damaged.
It's a training mag that gets dropped empty a fair bit, though never loaded. Still fairly new though. Perhaps the insert had gotten knocked and stuck depressed, I can't be sure, but I find that unlikely given that it was fully loaded. Still, a good reminder to always check the hole in the baseplate when grabbing carry mags.
I've heard of this happening with the old +2 baseplate, before the insert, but I thought the new ones were good to go. Now I'm questioning it a bit, though I don't particularly want to go loading up mags and repeatedly dropping them to test it.
Anyone else see this happen with the newest hardware?
