I live in Henderson and have a Nevada CCW permit. Moving from Florida (where I have a CCW permit), I was amazed at the "smoke and mirrors" of the "qualification process". As others stated, you only need to qualify with one revolver. However, each pistol must be qualified.
The "smoke and mirrors" I refer to is that there is no set of qualification requirements spelled out in the law. It's at the discretion of the person who is conducting your qualification.
I had to shoot single-handed from left and right, then dual-handed from both sides. I firmly expected to have to stand on one foot while whistling Dixie by the time we were finished.
The bad thing was that the instructor demanded that all ammo shot on his range must be purchased from him...his ammo is overpriced by at least 50%.
