His Last Vow
The following weapons were used in the television series Sherlock:
Dr. Watson (Martin Freeman) owns a SIG-Sauer P226R pistol in which Sherlock Holmes (Benedict Cumberbatch) occasionally uses the weapon. Owing to the strict firearms controls in the UK and the reduced insurance cost during filming, the Tokyo Marui P226R airsoft pistol was used as a stand-in, hence the finish and markings are mismatched. This same prop also shows up on several occasions in the hands of minor characters.
Trivia: Given Watson's military background, the P226 is likely meant as a stand-in for the SIG-Sauer L105A2, the British Army's former standard issue pistol. Yet, it is never explained that how did Watson manage to keep hold of his service piece as he had to surrender his weapon upon his discharge, given that Dr. Watson is not an active soldier anymore.
STI Edge (Cigarette Lighter)
The cabbie (Philip Davis) in S1E1 uses a novelty cigarette lighter disguised as an STI Edge.
A number of Glock 17 pistols are prominently seen in the hands of CIA agents and armed police officers in Season 2.
Two-Tone Glock 17
Detective Inspector Lestrade (Rupert Graves) uses a 3rd Generation two-tone Glock 17 at the end of S2E2.
Beretta 92FS Inox
Henry Knight (Russell Tovey) uses a Beretta 92FS Inox in S2E2 when he thinks that the gigantic hound is outside his home. Judging from the color and reflectivity of the finish, this is likely the Tokyo Marui airsoft replica of the 92FS Inox. Moriarty also uses a 92FS Inox during the second season finale.
M1911A1 (Unidentified Variant)
A hitman disguised as a repair man in S2E3 has a suppressed M1911A1 pistol stored in his tool box. Judging from the markings and the screws in the slide, this is likely a blank-firing replica.
Submachine Guns
Heckler & Koch MP5A3
Multiple H&K MP5A3 submachine guns, outfitted with Surefire flashlight fore-ends and EoTech sights are seen being used by the CO19 Armed Response Unit throughout the second season finale.
Rifles
AK Variant
During Dr. Watson's flashback to his tour in Afghanistan, an ANA soldier is seen using a variant of the AK-47.
AK-47
One of the terrorist at the end of S2E1 is armed with an AK-47 rifle. As with the P226, this is likely an airsoft gun.
L85A2
A small number of L85A2 rifles are seen throughout the series.
Heckler & Koch G36C
Some of the soldiers at the Baskerville Research Facility are armed with Heckler & Koch G36C assault rifles.
