I’ve loaded/unloaded a mag 30 times to see what would happen to the bullets. Some bullets lost quite a bit of elastomer, but none lost all of it.
Concerned, I contacted my agency’s factory rep and was told that as long as some elastomer is present, even if a bit flakes off, the bullet will still perform through barriers. Worst case, if the elastomer is completely removed, the only event it won’t perform as advertised is through auto glass.
I was also told current production G2 should have an updated elastomer tip that is more flush with the nose of the hollowpoint to help mitigate damage. Agencies that have received recent shipments of G2 (since October/November-ish) should have gotten this updated round.
