Came here probably only twice in my life. Once for some convention my friend was participating in (Anime..? lol) but most recently this past weekend for the Crossroads of the West gun show. There used to be the Rocky Mountains gun show at the South Point Casino but they no longer come to vegas so this was the next biggest one. We had arrived fairly early in the day around maybe 1000A. The main lot in front of the building was mostly full but still a decent amount of spaces left. There was a small double line waiting to buy their ticket. Parking was $5 per car. Admission was $14 - $1 coupon you can find online on their site.
Prior to entering the venue, I had expected the entire place be used but it was maybe half used. Nothing close to how the Rocky Mountain gun show was back then with tons of gun vendors. I had maybe hoped to buy the newly released Smith & Wesson M&P 2.0 9mm at a cheaper price than local shops but they were on average maybe $80 more than the lowest price at a near home local gun store. Ammo prices were fairly decent but my friend said he had found cheaper at another local store. For me personally, if you were to buy in larger amounts, and don't mind reloads, for 9mm 500 rounds, it was about $90. Pretty good if you are just a range shooter and not need anything specific. There was 1 main magazine seller, 1 main ammunition seller (there were smaller ones), and maybe 2 or 3 larger gun sellers.
Worth it? It wasn't for us. We do see people having some successful purchases but not as much as I remembered from another gun show.
Venue wise, fairly open place but small. Good for small events.
Funny thing was on the outside wall, it said something about by law, weapons are not allowed on the premises... except the fact this is a gun show.. LOL and people are walking in and out with guns xD
