Exactly, buying a guitar without trying first is what most people do an it's a big mistake.
The main point is that you might not even like the feel of the guitar. Maybe the neck is too fat for you, or too wide, or the frets are too big, or whatever... You could (and should!) even try other guitars, just because you can, you never know, maybe you'll find a beauty you'll fall in love with!
I know a lot of guys out there want a certain guitar because their favourite guitarists use THAT brand or THAT model... but your technique, your hand size, the length and thickness of your fingers, arms, etc may not be the best match for that guitar.
And don't be embarrassed about the trying the guitar. Go to the store, ask for a Les Paul Studio and ask someone from the store what other guitars with a similar sound they have in the same price range and try them all, you can even go every week and just try guitars until you make up your mind, after all it's a big investment and they wouldn't expect you to buy the 1st guitar you try or even worse, buy a guitar without trying it first
