T-Pain’s carry-on luggage didn’t make it onto the plane, because security agents found a gun in it … TMZ has learned.

Law enforcement sources tell us … the rapper’s bag was flagged during a main checkpoint screening at the Atlanta airport Friday, and when TSA agents inspected it, they found a loaded Smith & Wesson .380 inside.
