The Godfather II

Here is a list of all the locations for the level 2 and 3 weapons to complete the 'Welcome to the Gun Show', 'Gun Smuggler', and 'Modified Firepower' Achievements.

I've taken the list that TheSpiderHam666 provided for these Achievements, and rearranged all of the weapons. They are now organized by city, listed in the most likely order in which you will come across them in that city. There are a total of two (2) in New York, five (5) in Florida, and three (3) in Cuba.


NEW YORK
Level 2: Sawed-off: Corleone's Compound. From the inside of the compound looking at the front gate, you will see a hedge on the right you can burn with an arsonist. After he torches it you will find it right behind it.

Level 2: .44 Magnum Force: When attacking Carmine Rosato's compound in New York, go upstairs in the tiny foyer before you approach Carmine. The Magnum is clearly visible on a desk.


FLORIDA
Level 2: Silenced Pistol: Ryan Roth mission. Found during the mission where he sends you to rescue one of his soldiers.

Level 2: Spitzer Centerfire: Emilio's packing company. It is located on the rooftop just to the right of the owner; an engineer is required to cut the fence.
