Peace Tying

[joyeuse13.livejournal.com]

I've seen a few questions come up recently about peace-tying and the con weapons policy, and it occurred to me that since I'm actually doing a military sci-fi costume for the first time, I ought to know about things like this.

I know how to peace-tie a dagger or sword in its sheath, but guns are a new one for me. I picked up this little plastic doodad at the dollar store and spray-painted it silver, so there's no way it's a working gun, but I know from a distance appearances can be deceiving. Can anyone tell me if I need to do anything to this to set Security's mind at ease?
