A trey pound 7 is a .357 Magnum. Trey=3 and 5=Pound. 7 is the last number. Trey pound 7=Magnum. Cleveland is near New York, so we share the same slangs.
50 Cent Lyrics (Right Thurr Remix)
I got my trey pound 7 right hurr, right hurr
I'll shoot a nigga ass right hurr, right hurr.
I got my trey pound 7 right hurr, right hurr
I'll shoot a nigga ass right hurr, right hurr.
