Grand Theft Auto IV is the fourth numbered game in the popular Grand Theft Auto franchise, developed by Rockstar North and published by Rockstar Games.
The game was released in April of 2008 for PS3 and Xbox 360, with a PC version following in December of that year.
The RPG-7 is the only rocket launcher in the game and can be found occasionally in the game world; it is also given to the player during some missions.
The DLC episodes instead cast the player in the role of two minor characters from Niko's story, respectively starring biker Johnny Klebitz and Dominican gangster Luis Fernando Lopez.
The following weapons are seen in the video game Grand Theft Auto IV: WARNING! The standard handgun in Grand Theft Auto IV is visibly a second generation Glock 22.
It is (obviously) more powerful than the Glock, though the lower capacity make its superiority to the Glock a matter of opinion. It was likely based on a replica: note the missing magazine release and uneven coloration typical of poor-quality plastic.
Note also the incorrect short slide serrations (which appear closer to that of an earlier Mark VII variant).
