Everyone's favorite auction website has a water gun version of the 1911 listed every now and then. I just searched and there was one for about $10 US not including shipping. Search "VTG Auto-m" and you should find it if it's still there. I'm jealous, that one has water magazines and mine...
I'm planning on wearing mine in New Orleans at Voodoo fest and was concerned about getting through the gates with anything more spohisticated than plastic. I've been mulling it over and my best scabbard idea so far is to mod a pvc pipe with a heat gun and faux finish it. :)
I had the same problem and after hours of digging and phone calls I was informed by a vendor in New York that there was an error at the manufacturer level (Rosie's) with the item description and there were never any scabbards made or delivered.
