Nailed it.You can definitively tell which ones the Colt by the staking.
PSA has been screwing the pooch lately. I doubt a safety issue exists, but who knows how far down the food chain they have to source to be able to sell $79 bcgs.
This isn't the first one I've seen with that odd profile. PSA is just sourcing parts from the cheapest available vendor and selling them like hotcakes. It's probably a "functional reject" that another vendor refused to accept.
