The Walther PPK is seen throughout the film as a prominent weapon.
Stainless Walther PPK
Replacing the Beretta he used in the first film, Agent Johnny English (Rowan Atkinson) carries a stainless Walther PPK as his sidearm for much of the film.
Beretta 92FS Inox
Johnny English (Rowan Atkinson) briefly uses a Beretta 92FS Inox in the church to 'acquire' Patch Quartermain's (Tim McInnerny) wheelchair. This appearance of the gun is likely a tribute to the first film, where it was carried by English as his primary sidearm.
Beretta 92S
A Beretta 92S with black grips is seen in the weapon equipment storage of the Rolls-Royce in Switzerland. It can be recognised as a 92S by the magazine release at the base of the grip, it is not an original 92 due to the slide-mounted safety / decocker. Due to a continuity error, it is replaced with a newer 92FS model when English draws it in the Swiss stronghold.
Beretta 92FS
Johnny English (Rowan Atkinson) uses a Beretta 92FS in Switzerland (replacing the older 92S model seen when he and Tucker are arming up).
Browning Hi-Power
Patch Quartermain (Tim McInnerny) has a Browning Hi-Power mounted on his wheelchair. After English 'acquires' the chair and uses it to escape pursuing MI7 agents, he uses the gun to threaten disabled people and get past them to get to an elevator.
In English's flashback to the failed mission in Mozambique, an assassin (Chris Jarman) is seen using a compact model of the Jericho 941 to kill the newly elected President of Mozambique.
Unknown Colt M1911 variant
Simon Ambrose is seen holding an unknown Colt M1911 variant in the lab. It has an adjustable rear sight and an extended beavertail.
Rifles
SIG SG 552
The guards at the stronghold in Switzerland all carry short-barreled SIG SG 552 assault rifles with pronged flash-hiders and standard diopter sights.
Norinco Type 56-1
A guard at the Presidential Palace in Mozambique is seen with a Norinco Type 56-1.
Heckler & Koch SR9
MI7 snipers fire suppressed Heckler & Koch SR9 rifles at Johnny English in the church.
Machine Guns
FN M240G
A technician at the Toy Cupboard is seen working on an FN M240G machine gun.
The first time we see the "Killer Cleaner" (Pik-Sen Lim), her weapon is a rifle assembled from a vacuum cleaner.
"Golf Club Gun"
The Killer Cleaner then uses a gun hidden in a golf club.
"Golf Bag Minigun"
The Killer Cleaner then fires a minigun built into her golf bag at English and Tucker.
"Lipstick Gun"
Since Vortex initially had intended to use Pegasus (Gillian Anderson), the weapon that is used in the attempt on the Chinese Premier's life is a lipstick gun.
"Camera Dart Gun"
English uses a dart gun disguised as a digital camera. He fires it once in the lab, and once again in Hong Kong to stop a fleeing inflatable boat.
"T2 Ground to Air Missile Launcher"
English mistakenly uses the "T2 Ground to Air Missile Launcher" near the end of the film. Disguised as an umbrella, English thought it was a "D7 Bulletproof Shield".
Deleted Scenes
Micro Uzi
In a deleted scene, Slater (Burn Gorman) uses a Micro Uzi to attack English and Tucker's Rolls-Royce.
Heckler & Koch HK69A1
In the same deleted scene, Slater switches to a Heckler & Koch HK69A1 grenade launcher after discovering that the Rolls-Royce is bulletproof.
Heckler & Koch G36C
In a deleted scene, a technician walks past English and Ambrose with a Heckler & Koch G36C in each hand.
Glock 34
In an extended scene, the image of a Glock 34 is seen next to an image of Artem Karlenko (Mark Ivanir), presumably supposed to be his personal sidearm.
