Error! Sorry but wrong...
I believe the OP is new to guns...
So investing a bit before you buy will save you in the long run.
The drill you want to do is test them out. Basics...
At the gun store a gun may feel good in the hand but when you go to the range you may not like how it handles (recoils and functions). If you bought the gun... you just spent a lot of money learning not to buy a gun simply by looks and feel at the gun store.
Going to the rental range - you want to keep it simple. Find what caliber you like and make/model of gun feels good in the hand while shooting it.
So, load, unload, function test, work the mechanism of how it works, safeties and decocker if it has one... Then shoot it. Shoot at least 3-10 rounds in each gun. This will give you an idea how it "feels" in your hands... recoil and sights.
Just like test driving a car... one can not most times test shoot a gun... Renting them will save you a lot of headache and remorse... So, invest and take your time. Rent the whole gun rental case and buy lots of ammo.
I recommend to set aside at least $60-$150 to do this well. Typically, $20 for range fees, $20 for rental guns, $5 for targets, $20-100 for ammo.
