The Walther PPK is seen throughout the film as a prominent weapon.
Walther PPK (Stainless)
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 movie.
Beretta 92FS Inox
Johnny English (Rowan Atkinson) briefly uses a Beretta 92FS Inox in the church to 'acquire' Patch Quatermain'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 gearing 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 get past other disabled people to get to an elevator.
In his flashback to the failed mission in Mozambique, an assassin (Chris Jarman) is seen using a compact version of the Jericho 941 to kill the newly elected President of Mozambique.
Unknown Colt M1911 variant
Simon Ambrose is seen handling an unknown M1911 variant in the lab. It has an adjustable rear sight and an extended beavertail.
Rifles
SIG SG 552
Guards at the stronghold in Switzerland all carry short-barrelled 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 an Norinco Type 56-1.
Heckler & Koch SR9
MI7 snipers fire at Johnny English in the church with suppressed Heckler & Koch SR9 rifles.
Machine Guns
FN M240G
A technician at the Toy Cupboard is seen working on an 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 on Johnny and Tucker with a minigun built into her golf bag.
"Lipstick Gun"
Since Vortex 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"
Johnny is issued 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.
"T2 Ground to Air Missile Launcher"
Johnny mistakenly uses the "T2 Ground to Air Missile Launcher" at the end of the film. Disguised as an umbrella, Johnny thought it was a "D7 Bulletproof Shield."
Deleted Scenes
Micro Uzi
In a deleted scene, Slater (Burn Gorman) attacks Johnny and Tucker's Rolls-Royce with a Micro Uzi.
Heckler & Koch HK69A1
In the same deleted scene, Slater switches to a HK69A1 grenade launcher after discovering that the Rolls-Royce is bulletproof.
Heckler & Koch G36C
In a deleted scene, a technician walks past Johnny and Simon 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 Karlenko, presumably supposed to be his personal sidearm.
