I liked how the first-gen LCI on the Ruger MKIII could actually cause an AD
seems that if the LCI was hit hard enough, it could actually dent the rim of the case just like the firing pin did, and the round doesn't care if the firing pin or an LCI caused the primer compound to be ignited, bang goes the round. Ruger ended up changing the design from a one-piece LCI to a two-piece LCI so that would be less likely to occur.

an replaced with a faux LCI
