James Howlett (Hugh Jackman) before he is "Wolverine" is seen carrying a British 1853 Enfield as a Union soldier during the Civil War. Several Union soldiers are using Enfield rifles too.
James Howlett (Hugh Jackman) is seen armed with a Colt Model 733 while serving in Vietnam. This gun was not available at the time and is an anachronism. Instead of a Colt 733, he should be using a Colt XM177 instead.
Agent Zero (Daniel Henney) uses a Beretta 92FS Inox fitted with a sound suppressor to shoot a cheap cigar in half while it is in Logan's (Hugh Jackman) mouth when he confronts him in Canada.

Browning M2HB
A Humvee in hot pursuit of Wolverine (Hugh Jackman) fires a Browning M2HB at him as he drives away on a motorcycle. Wolverine then does a hard turn and flips the Humvee with his claws. One of the guns he destroys by chopping off the barrel with his claws, while another he uses to fire at the helicopter before it is destoyed by a rocket. The Browning M2HB is also seen mounted on the Higgins boat in the opening credits.
The helicopter in pursuit of Wolverine (Hugh Jackman) has a pintle-mounted GE M134 Minigun, which the gunner uses in an attempt to kill him. The sound effect of the gun firing is far too slow for its actual cyclic rate (in fact, they use the same sound report when depicting the M2HB firing!).
US soldiers during Vietnam hold up Victor Creed (Liev Schreiber) with M16A1s after he kills his commanding officer. When he and Howlett (Hugh Jackman) are tied up to posts and shot by a firing squad, they too are using M16A1s. Some of the M16A1s are fitted with 30 round magazines, which wasn't available at the time and the 30 round magazines for M16 type weapons came after the United States was directly involved in the Vietnam War. It was however, used by the ARVN in the Mid 1970s.
Actually the 30 round mags for the M16A1 did see service in Vietnam in the late 60's. From my knowledge they came into circulation in the US military in like 1967 or so.
Victor Creed (Liev Schreiber) is seen with an M1911A1 in his holster while serving in Vietnam and many Vietnam War soldiers also have some holstered. Col. William Stryker (Danny Huston) intimidatingly flashes one in his holster when he has Kayla Silverfox (Lynn Collins) explain his plot to Wolverine (Hugh Jackman).
David North/Agent Zero (Daniel Henney) uses an SVD Dragunov to snipe the two kind old people who helped Wolverine (Hugh Jackman) out and then blames the deaths on him as an excuse to attack him.
Col. Stryker (Danny Huston) uses a stainless Ruger Redhawk (not the newer Super Redhawk, as indicated by the ejector shroud) loaded with adamantium bullets to shoot Wolverine (Hugh Jackman) five times, two of which are fired into his skull, erasing his memory.
Ruger Redhawk - .44 Magnum.
AKM
African soldiers seen during the first Department H mission in the film use AKMs to fire on the team. We also see them used by Stryker's men on the island. Some of the rifles are clearly Norinco Type 56 rifles.

Rather than having the underfolder pig sticker Bayonet assembly, this has the standard Bayonet lug underneath the gas block as the AKM and later variants.File:Akminred.jpgAn African soldier is surprised of Wade's super powers with a Norinco Type 56 circled in red.
Some also use the folding stock AKMS. Many members of the team have them slung over their backs, including James Howlett (Hugh Jackman).
Thomas Logan (Aaron Jeffery) uses a 12 Gauge Double Barreled Shotgun to kill John Howlett (Peter O'Brien) at the film's start. The old man who takes in James Howlett (Hugh Jackman) after he is turned into Weapon X also uses a side-by-side when he searches for him in his barn. One is also seen in the African's desk as he tries about to grab it to shoot Stryker and his team until Wraith pushes his hand away.
A German soldier during WWI shoots Victor Creed (Liev Schreiber) with a Mauser Gewehr 1898 rifle. James Howlett (Hugh Jackman) briefly grabs one and tosses it in the air for Victor to use as a melee weapon during the "back-to-back" scene.
