Early on in the film Sergeant Nicholas Angel (Simon Pegg) fires a round from his Heckler & Koch G36C fitted with a standard G36 carry handle, laser pointer and tactical flashlight during a CO-19 operation.
Norinco Type 56-1
During the opening scene Sergeant Nicholas Angel (Simon Pegg) fires his G36C into "a crack-head holding a Kalashnikov" (Garth Jennings). The type of AK-47 the crack-head was armed with appears to be a Chinese-made, folding stock Norinco Type 56-1 assault rifle.
L1A1 SLR
When Sergeant Nicholas Angel (Simon Pegg) takes on the town, he brings the British variant of the FN FAL, the L1A1 SLR.
Steyr-Solothurn S1-100/MP34 submachine gun
Joyce Cooper (Billie Whitelaw) uses a World War II-vintage Austrian Steyr-Solothurn S1-100 (or better known as the MP34 in WWII German service) submachine gun when Nicholas Angel (Simon Pegg) starts to take on Sandford. PC Doris Thatcher (Olivia Colman) uses the same S1-100/MP34 for the rest of the film.
Lee-Enfield No.1 Mk III* SMLE
Sgt. Tony Fisher (Kevin Eldon) uses a Lee-Enfield No.1 Mk III* bolt-action rifle during the supermarket shootout. A number of No.1 Mk III* rifles (along with a couple of Lee-Enfield No.4 rifles) were also found in Arthur Webley's (David Bradley) basement earlier in the film.
Seargent Nicholas Angel (Simon Pegg) uses a Taurus PT92 AF as his main sidearm during his assault on the town, sometimes using it akimbo style along with his Jericho 941 "Baby Eagle".
Jericho 941 "Baby Eagle"
A tutone (stainless frame, blued slide) Jericho 941 "Baby Eagle" is used by Sergeant Nicholas Angel (Simon Pegg) in the supermarket and pub shootouts, akimbo style with his Taurus PT92 AF.
Smith & Wesson Model 629
A revolver is seen in Angel's hip holster, which he never draws but appears to be a Smith & Wesson Model 629.
Nicholas Angel's (Simon Pegg) partner, Danny Butterman (Nick Frost) uses a Winchester 1300 Defender provided by Angel during the shootout in the town. The Model 1300 Defender in the movie is fitted with a synthetic stock, tactical flashlight in the foregrip, and spare 12 Gauge shell holders. Doctor Robin Hatcher (Stuart Wilson) also uses a Defender which he pulls from the trunk of his car. He fires several shots at Angel when he first enters the town and holds both Angel and Danny at gunpoint before Danny blows his foot off.
Mossberg 500
PC Seargent Nicholas Angel (Simon Pegg) uses a Mossberg 500 shotgun with a muzzle choke and 18" barrel when he assualts the town. Mary Porter is also seen using a Mossberg 500 with a 28" barrel when Danny and Angel assault the pub. DC Andy Cartwright (Rafe Spall) takes her gun for himself and uses it to aid Angel as he assaults the grocery store.
Smith & Wesson 5906
Danny Butterman (Nick Frost) uses a Smith & Wesson 5906 as one of his sidearms, sometimes firing it akimbo with a Charter Arms Snub. He is seen using it during the pub shootout and during the car chase to shoot at Simon Skinner's (Timothy Dalton) car. His father, Inspector Frank Butterman (Jim Broadbent) gets ahold of it in the final scene in the mini-village and threatens his son with it. Danny then retains the weapon while Frank runs off - unwilling to shoot his own father, Danny angrily fires the S&W into the air while lying on his back (spoofing a scene from Point Break).
Charter Arms Snub (Unknown)
Danny is seen wielding a snub nose which looks like a Charter Arms model, mainly akimbo style with his Smith & Wesson 5906.
Double Barreled Exposed Hammers Shotgun
A Double Barreled Exposed Hammers Shotguns is seen in the hands an old lady who tries to fire it at Angel when he first enters the town, being drop kicked in the face before she can reload. DS Andy Wainright (Paddy Considine) is also seen using this shotgun during the shootout in the grocery store.
Reverand Phillip Shooter ((Paul Freeman) uses a pair of NAA Mini-Revolvers mounted on slides in his robes to shoot Angel (Simon Pegg), who is saved by his bullet-proof vest from being fatally wounded.
Colt 1851 Navy
Inspector Frank Butterman (Jim Broadbent) uses two engraved Colt 1851 Navy revolvers with gold cylinders when he confronts Angel in the pub. Since Frank seems to be a bit of a Western lover, these guns seem to fit him well.
Winchester Model 1887
A Winchester Model 1887 with a large lever loop, sawed-off barrel, and sawed-off stock similar to the one used in Terminator 2: Judgement Day is used by Mr. Treacher (Tim Barlow) when Nicholas Angel (Simon Pegg) first takes on the town of Sandford. Since Winchesters aren't made anymore and are harder to find, this is likely a replica model such as a Chinese Norinco YL1887L shotgun, sawed-off "T2" style.
Blunderbuss Flintlock
At the end of the film, Tom Weaver (Edward Woodward) uses a Blunderbuss Flintlock scatter shot to attempt to kill Sgt. Angel before Danny Butterman dives in the way.
Air Rifle
While on duty during the town's festival, Danny begs Angel to try out at the Rifle Range. Angel picks up an Air Rifle and takes out all six man targets in about two seconds. Anyone who has ever uses one of these air rifles should know that they are single shots that takes at least 5 seconds to break open and cock the spring and load it. Angel must be an uber-shooter in order to accomplish such an immposible task.
Beretta 92SB (stage prop)
Eve Draper (Lucy Punch) uses a stainless steel Beretta 92SB stage prop to "kill" herself when playing Juliet Montague in the horrendous "Romeo & Juliet" play.
M14 (M21)
The lady who owns the conveniance store (name not known) tries to snipe Angel with an M14 Rifle fitted with a scope. Luckily for him, she misses every time and is forced to stop when her rule of 1 school student in the store at a time is broken as Angel herds the children through the door.
Seen in one of the boxes Angel carries to the evidence room is a Mk. 2 hand grenade.
SIG-Sauer P226
When Danny and Angel watch Point Break, the infamous scene is shown when Johnny Utah (Keanu Reeves) aims his SIG-Sauer P226 pistol at Patrick Swayze's character and fires his gun empty into the air, a scene which is later replicated by Danny and his father.
The most unique item in Mr. Webley's basement is an old Sea Mine, which is said to be deactivated but Tom Weaver is unlucky enough to prove otherwise when Angel kicks him into it and it blows up the entire police station, only killing him though.
