The MP5 is a submachine gun featured in all the games in the GTA series since GTA Vice City. In GTA Vice City, it is referred to as MP, while in all other GTA games it is called SMG. In GTA V it is manufactured by Hawk and Little.
"Hits harder and is more controllable than a Micro SMG, but has fewer rounds in the magazine. ...The professional's choice."
— Description in GTA CW
The SMG is one of the most powerful submachine guns in the GTA series, with devastating effects to both the player and non-player targets alike. It is arguably a better substitute for the Micro Uzi and Micro-SMG, holding more damage per round. However, like the Micro-SMG, the MP5 has the disadvantage of disallowing the player from discharging the weapon while running, allowing the player to only stand or stride while taking aim or shooting. Since its inception in GTA Vice City, the weapon is favored by both the FBI (and GTA IV's FIB) and GTA IV's NOOSE tactical units as a weapon of choice. All renditions of the MP5 hold 30 rounds per magazine.
Each MP5 rendition has a variant in the GTA games. GTA Vice City and San Andreas feature an MP5A3, and GTA Liberty City Stories features the MP5K which looks a little lengthier than the other renditions. In Vice City Stories, the SP89 (a civilian version of the MP5K) makes an appearance, but the model also contains parts of the MP5A3, MP5K and MP5SD. In GTA IV, the MP5 is heavily modified and resembles the look of an MP10. In GTA Chinatown Wars the MP5 is called the SMG, just like any other rendition. In GTA V, the model that appears is the MP5A3 variant (signified by the straight pistol grip, three position Safe, Semi, Full trigger group and retractable stock). The MP5 is however fitted with a rectangular handguard supposedly from a Taurus MT-40, has angular iron sights similar to those from a CZ Scorpion Evo 3 A1 and appears to have much shorter magazines in comparison with the real-life MP5A3.
Customization (GTA V)
Flashlight (provides ilumination when aiming) - $2050
The SMG can be purchased at the back-alley gun shops for $2500 and each additional magazine costs $150. It can be purchased from Little Jacob for $1750 and each additional magazine will cost $20. It is basically the most used weapon on multiplayer and a good weapon for single player also. It is a 2 hit kill with head-shots on single player and multiplayer. It has about double the range of an Uzi and almost the range of an AK, but not as much range as an M4. This weapon is good for drive-bys and car chases as it has an high rate of fire and a 30 round magazine, but the Uzi is more suited for that purpose and this gun is more suited for attacking on the ground.
Schottler - Can be found on an air-conditioning duct-work in an alley between Boone Street and Dillon Street. This pickup isn't so tricky to get to: walk the alley opposite hJacob's home just to the dead end, jump to the left edge. you can't pull onto the roof near the roof windows so move along this edge left then pull up. It is where the mission Jamaican Heat takes place
Acter Industrial Park - Can be found on the seventh floor of an observation platform of a RON Oil refinery on the southern side of the island. This is a particularly long way to go to get this weapon, however, and is not recommended.
GTA Chinatown Wars
Available in AmmuNation.net after the Fully-Crocked Upgrade is purchase.
A shorter version of the weapon, the MP5-K, was cut from Grand Theft Auto: Vice City. Model and textures for the weapon still remain in the game files (mpfshrt.dff and mpfshrt.txd). The weapon can also be seen in the intro of the game, being used by one of the men who ambush the drug deal.
The initial release of Grand Theft Auto: Vice City, the submachine gun was called MP5, but due to a licensing flap, later version (Double Pack) was named to just MP.
GTA Liberty City Stories
The GTA Vice City/San Andreas MP5 was meant to return to Liberty City Stories. Leftover textures exist in the files.
GTA Vice City Stories
The SP89 is anachronistic to Grand Theft Auto: Vice City Stories, which takes place in 1984, while this variant of the MP5 was not made until 1989. In game it is fully-automatic, while in real life it is semi-automatic. However, it may be illegally custom converted to fully-automatic, as its much easier than to obtain a civilian version than a normal version.
Both sides of GTA IV's MP5s feature "MADE IN SCOTLAND" markings (mirrored on the left side), alluding to GTA IV's Scottish developer Rockstar North.
You can get this weapon in the beginning of the game after unlocking the gun shops. Attack the manager and he will call out his friends to help. Two of them will be holding the MP5, and one will hold the Combat Shotgun, so be careful. After killing them all you can take the MP5 from them.
In GTA IV, the reload animation is one second longer when the player is crouched. When the player is reloading in the position, they will pull a "lever" on top. This is inaccurate because nothing is pulled on top of the gun in real life; even this "lever" isn't visible. This is most likely a glitch.
In the beta version of GTA IV, there was a different looking MP5 as seen in the picture of the right. It has a stock attached to it and it has more resemblance to the MP5A3 rather than the MP10. The model appears to be very similiar to the MP5 featured in the game Counter Strike 1.6.
The GTA IV rendition have a flashlight, but it never been used throughout the game.
In GTA V, the standard magazine for the SMG is modeled after a 15-round magazine (even though it holds 30 rounds in-game), and the extended magazine is modeled after a 30-round magazine (holding 60 rounds in-game).
Like the MG, it has ample space on its railed fore-end to mount a Grip, but is unable to do so.
GTA V is the only game where you cannot use the MP5 in a drive-by shooting, as GTA V's model is too large to be used as a drive-by weapon.
The reload animation is similiar to the HK Slap; a somewhat common and popular way to empty reload the MP5 by 'slapping' the charging handle of the weapon to lock it back into place.
