The classic cropped shotgun from GTA Vice City is now in your GTA San Andreas, the model was exported directly from there, and the icons and details are finalized for the style of San Andreas.
Fun fact: The shotgun was already present in the developer version of GTA San Andreas, the proof of that is the identifying name ";buddyshot" in the file "object.dat", since it was cut as a model from the game, this mod can serve as its restoration.
You can either install it normally (it will replace the shotgun), or add it without replacement as an addon! I recommend installing it for the best experience.
NOTE: If you post this mod on another site, leave the author a thank you.
