I've never heard or read of any specific restrictions. We go into the El Pasos fairly often, and we always bring along the shotguns in quail season, but wear sidearms in holsters all year round. We go there for prospecting, as opposed to hunting, but it isn't unusual to kick up game while you are off the beaten trail. I certainly wouldn't recommend carrying or shooting ANY weapon in Redrock Canyon Rec Area, and Last Chance Canyon is getting pretty crowded, too. Carry good maps and be sure you know where your shots are going to fall.
