TGT Scams?

Hey y’all, just tried out TGT, and found a weapon I want to buy. The gent isn’t asking for me to send money, just a meetup and cash exchange deal. I saw warnings about scammers, and was curious what y’all meant by that, and if there’s red flags I should watch for. Thanks!

Edit: I got it, and the gent was super cool, and was a steal. I’ll post when I go to a range next. Thank you all for your help !! :)
