Hiya!
Here are some links for you:
http://www.bigrenoshow.com (in August)
The Boomtown show (May 11-13) was cancelled.
According to this:
http://www.nsrpa.us/gunshows.html there's supposed to be this show:
The Big Reno Show
Lou Fascio, Inc.
Grand Sierra Resort
Reno, Nv.
Fri. and Sat. 9-6, Sun. 9-3
May 11-13, 2007
But you'll have to verify that -- it seems to conflict with the cancelled one.
There may be shows in both Carson City and Gardnerville, but I'd have to hunt for those.
Stores?
Two shops that carry 1911s come to mind:
SILVER STATE ARMS
3020 Kietzke Lane
Reno, Nevada 89502
775-827-0303
Sportsman's Warehouse #123
3306 Kietzke Lane
Reno, NV 89502
775-828-1500
They're quite close together, Sportsmans is right by Ashley Furniture at the Moana Lane exit off 395, and Silver State is just North of there on Kietzke.
Sportsmans is open 7 days/week, Silver State is open 6 days.
Bizarre Guns (775-685-4867) in Sparks may also have 1911s, but I don't have a clear recollection of that. They're tricky to find, so pay attention if you ask for directions. The guy at the counter is often a bit of a curmudgeon, but if you can overlook that they have a good selection.
