i already posted about something similar a few weeks ago... but i went to turners outdoors and asked about UOC and the outdoors clerk suggested that i should not UOC because u would be hassled. he went on about how he would never UOC because he dont want to be bothered by dealing with the E check. at the end, had i not been informed about the law and this forum, as a customer interested in defense, i would probably not UOC.
me and my girlfriend just yesterday, UOC into turner's and indeed, the workers there were nervous except for the store owner, a large old man. he came to the front desk to had us check in our weapons... which was basically a receipt stating what our gun was. we UOC without a problem.
