I called the one local indoor range that has a G30 to rent, and it'll run me about $70 to rent one for an hour. That includes the range fees, rental buying their ammo and the second person they require to rent a handgun. Why the second person you ask? As I was told, it's in case you're not familiar with guns, so you don't hurt yourself. I told the kid that I'd managed not to shoot myself in the last 40 years, but their store their rules. So my wife will go and practice with her PT111, while I try out the Glock.
The public indoor range around here rents handguns for $10/hr, range fee of $17/hr, and you have to buy their ammo. You only need a certified instructor if you don't already have a handgun permit.
