Same here. OC'd in Cabela's several times with no issues.
One time it was very crouded, I mean shoulder to shoulder crouded, I was in the ammo section looking around and I thought I heard a guy whisper to his friend, "Yeah, I'd say something". He may have been talking about me or maybe not.
I live about 15 miles from Cabela's. Bought my P90 there and a Barretta CX4 Storm, 9MM. Sweet gun.
