More practical is there is a ten round limit on magazines, few places off limit.
Pretty sure there is no capacity limit in NM. They were trying for 9, but I believe it failed.
From what I’ve seen of NM, is can be a very pretty state from a geography perspective but the towns are mostly a total dumpster fire. I’ve always wanted to explore the NM Rockies more, but every time I drive through the state I’m ready to leave.
