My concealed carry instructor was a retired Spfld police. He was their firearm instructor for 11 or 12 years. He told us open carry was legal, but not advised in Spfld (it could cause citizens to become alarmed). My husband works with a fellow who is a youngretired policeman (car accident & couldn't pass physical). He told my husband it was legal and that it certainly never bothered him when he saw someone carrying open. He said the advantage to CC was you could get by with going into posted businesses, where you couldn't OC there. We would sincerely like to OC. I think all law abiding gun owners should. I believe once 'the public' gets used to seeing it, it would be no big deal. That is certainly the case with a lot of undesireable stuff! Anyway, with our LEO shortage, it might reduce the growing crime rate!!!!
