Can you buy Solana on MetaMask?

Can you clarify if it's actually possible to purchase Solana directly on MetaMask? I'm under the impression that MetaMask is primarily a wallet for storing and managing various cryptocurrencies, rather than a platform for trading or buying them directly. So, are there any steps or methods I should be aware of if I want to acquire Solana and store it in my MetaMask wallet? Or should I be looking at other platforms to make the initial purchase?
