Trouble in Terrorist Town: Pointshop and Weapons

I am fairly new to LUA and I am quite stuck. I am using _Undefined’s pointshop addon, and I was wondering how you could make it so that whenever you spawn on a new round, you start with a purchased weapon. I’ve seen other servers with this function, and I would like to be able to use this.

TTT is old, overused, and a tumor to the GMod Community. I suggest not using TTT period

That’s for permanent weapons. For one-round, take away single us and replace equip and holster with buy and sell respectively
