Yakuza 4 (龍が如く4 伝説を継ぐもの Ryū ga Gotoku fō: Densetsu o Tsugumono, lit. "Like a Dragon 4: Successor of the Legend") is the fourth entry in the Yakuza series, published by SEGA in March 2010, with the western releases following a year later. A remastered version for the PlayStation 4 was released in January 2019 in Japan and October 2019 worldwide, the latter being part of the Yakuza Remastered Trilogy. The trilogy has also released on Steam, Windows 10, and XBOX Game Pass in January 2021. Yakuza 4 is the first main entry in the series to feature multiple player characters as well as adding in the ability to explore underground spaces and rooftops.
The following weapons appear in the video game Yakuza 4:
Makarov PM clone
This Makarov PM-type pistol with an extended barrel and ring hammer is massively popular with gangsters in the Yakuza universe. It may also be picked up in fights as the "Shoddy Pistol" in battles, or purchased and equipped by Kiryu and Saejima as the "9mm Automatic Pistol." There is also a multicoloured version called "Mr Random" whose bullets have random effects. This particular firearm can be obtained through modding the "9mm Automatic Pistol."
A heavily customized SIG Pro is used by antagonist Takeshi Kido. It features wooden grips and a vented barrel and slide. It also appears to lack a de-cocking lever. This would make it very difficult to make the weapon safe. The user would either have to unload it and pull the trigger, or the far more dangerous manoeuvre of holding the hammer back, pulling the trigger, letting the hammer off slightly, releasing the trigger, and then the hammer so that it would go back into safe mode.
SIG-Sauer P226/Heckler & Koch USP
This hybrid of an SIG-Sauer P226 with details from the Heckler & Koch USP is used by player character Masayoshi Tanimura's superior officer Satoshi Hisai. He is instructed to use it to kill Tanimura himself, as well as Tanimura's foster father Zhao and Zhao's daughter Mei Hua, but unable to betray his friend and murder innocent people, he uses it to take his own life instead. As with other games, this model is referred to as a "CZ75" for some reason.
This misshapen SIG-Sauer P230 from the previous game appears in the hands of this game's main antagonist Hiroaki Arai. As mentioned in the previous game, it barely resembles a P230, but it is referred to as such in the game files and since it does not resemble any other gun more closely, we'll go with that. Fortunately it no longer has the garish golden finish, instead being black. It is also seen in a revelation.
Nambu Model 60/Smith & Wesson Model 36
Another very widely used model in the Yakuza series is this hybrid of a Nambu Model 60 with parts such as the barrel and grips from a Smith & Wesson Model 36. Tanimura is armed with a Model 60 but he cannot use it in fights except as a taunt. Masaharu Ihara has a special version of this gun, referred to in the game files as an "SNS," short for "Saturday Night Special." This is a term used for a cheaply-made gun perceived to be used by criminals. Although the model is no different from the police-issue revolvers in the game, the texture has been changed to give the appearance of tape over the handgrips (although this is mostly obscured by Ihara's hands in the game.) It can also be purchased and equipped as the "Double Action Revolver."
Nambu Model 60
Additionally, the distinctively-shaped butt of the Model 60 is seen in the holsters of police officers in the game.
Smith & Wesson Model 10
A Smith & Wesson Model 10 with a 3" barrel is one of the revolvers used by Taiga Saejima in his 1985 massacre of the Ueno Seiwa family.
Smith & Wesson Model 10/19
What appears to be a combination of the Model 10 frame (given the lack of adjustable sights) with the 6" barrel from a Smith & Wesson Model 19 is another of the three revolvers used by Saejima. This is not an implausible mod to do to a Model 10, as the .357 magnum barrel is essentially a more robust version of what would be found on a .38 special revolver. It would however require the lowering of the front sight to compensate, but that too appears to have been done on the game model.
Smith & Wesson Model 10/Colt Detective Special
Additionally, a version of this gun with a barrel (but not the front sight) based on the third-gen Colt Detective Special appears in the game. It also features a handgrip adaptor.
The Baikal MP-133 shotgun once again appears in its various guises: the black "Broken M1985" and silver "Expulsion S-12" can be purchased from the Weapon dealer. The former is also available in a weapon pack from Bob. The sawn-off "Shoddy Shotgun" is only usable during battle segments and the final two guises, the "Slime Gun" and "Spark Gun," can be modified from the standard shotguns at Kamiyama's weapons workshop with the right materials. The former is the same model as the "Shoddy Shotgun," whereas the latter has a pistol grip that, as always, the player characters can't figure out how to use properly. Optional boss GG is able to fire the "Shoddy Shotgun" one-handed whilst crouching.
Returning from Yakuza 3 is this hybrid of a Ingram MAC-10 and the front grip and (incorrectly collapsed) stock of a Brügger & Thomet MP9. Unlike its predecessor however, the gun can now be purchased and equipped by Kiryu (although not any of the other player characters.) Although powerful, the effectiveness of this weapon is reduced by the firing animation, which involves the user rotating in a slow arc from side to side. The weapon store refers to this gun as an "assault weapon." It should be made clear that the term "assault weapon" is a US legal term and has no relevance to Japanese gun control legislation, nor does it actually have any bearing on the type of gun that it is. In reality, the "assault weapon" regulations mostly banned features that politicians and members of the public that didn't know much about guns thought "looked scary," rather than things that actually affected the function of the weapon or how it is used.
Remington M24A2 SWS
A prison guard appears with this weapon during Saejima's prison break with Goh Hamazaki. This is identifiably the same model that makes a brief appearance in Yakuza: Dead Souls, which was released the following year. It has a laser scope, using a similar gameplay mechanic to games like Uncharted: Drake's Fortune, where the player gets shot after standing in the line of sight for a few seconds. Helpfully though, the laser transitions from green to red to indicate when the sniper is about to fire. The game model lacks a handle for the bolt.
